| #1 AEM; a-ETHYLMESCALINE; 2-AMINO-1-(3,4,5-TRIMETHOXYPHENYL)BUTANE; 1-(3,4,5-TRIMETHOXYPHENYL)-2-AMINOBUTANE SYNTHESIS: To a solution of 45 g 3,4,5-trimethoxybenzaldehyde in 1.2 L IPA, there was added 125 g nitropropane and 67.5 g t-butylammonium acetate and the reaction mixture was held at reflux for 16 h. This was poured into 6 L H2O, and extracted with 2x250 mL hexane. The pooled extracts were stripped of solvent under vacuum giving a residue that slowly set to a crystalline mass. On filtering, there was obtained 9.4 g of a crude yellow product which, on recrystallization from hexane provided 8.7 g of slightly sticky bright yellow crystals of 2-nitro-1-(3,4,5-trimethoxyphenyl)butene-1, with a mp of 71-73 deg C. A second recrystallization from hexane gave fine yellow crystals with a mp of 72-73 deg C. Attempts at the preparation of this nitrostyrene by the more conventional methods with ammonium acetate in acetic acid led either to the formation of a white product C23H30N2O8 which was composed of a molecule of the nitrostyrene, one of the benzaldehyde itself, and a molecule of ammonia, or to 3,4,5-trimethoxybenzonitrile, from reaction with the decomposition products of nitropropane. A stirred suspension of 5.9 g LAH in 310 mL anhydrous Et2O was held at a gentle reflux in an inert atmosphere. A solution of 8.5 g 2-nitro-1-(3,4,5-trimethoxyphenyl)butene-1 in 125 mL Et2O is added drop-wise over the course of 0.5 h. The reaction was maintained at reflux for 6 h, then cooled, and the excess hydride destroyed by the cautious addition of 300 mL 1.8 N H2SO4. The phases were separated, and the aqueous phase brought to a pH of 6 by the addition of a saturated Na2CO3 solution. The neutral solution was brought to a boil, and clarified by filtration through paper. To the hot filtrate there was added a solution of 8.9 g picric acid in 100 mL boiling EtOH. The mixture was stirred and cooled, with the formation of a heavy yellow crystalline mass. After standing in the ice tub for several hours the mixture was filtered, providing 8.0 g of the picrate salt with a mp of 176-181 deg C from H2O. A solution of this salt in 300 mL boiling H2O was treated with 60 mL concentrated HCl. On cooling, there was a deposition of picric acid, which was removed by filtration. The aqueous filtrate was washed with 3x50 mL nitrobenzene, then with 3x50 mL Et2O. The pH was brought above 9 by the addition of aqueous NaOH, and the filtrate was extracted with 3x100 mL CH2Cl2. Removal of the solvent from the pooled extracts gave a nearly colorless oil, which was dissolved in 300 mL anhydrous Et2O and saturated with hydrogen chloride gas. The white crystals of 2-amino-1-(3,4,5-trimethoxyphenyl)butane hydrochloride (AEM) were removed by filtration, Et2Owashed, and air dried. They weighed 4.72 g. DOSAGE: greater than 220 mg. DURATION: unknown. EXTENSIONS AND COMMENTARY: The extension of the two-carbon chain of mescaline by alpha-methylation to the three carbon chain of TMA approximately doubled the potency of the compound. And it was felt to be a completely logical possibility that, by extending it one more carbon atom, to the four carbon chain of alpha-ethyl-mescaline, it might double again. And following that logical progression, the doubling of potency with each additional carbon atom, the factor would be 2 to the 7th power by the alpha-octyl (or 256x that of mescaline, or a milligram as active dose) and with a side chain of a 70-carbon alkyl group (alpha-heptacontylmescaline) it would take just a single molecule to be intoxicating. This was rich fantasy stuff. As an active compound, just where would it go in the brain? With an 80-carbon side-chain, would one-thousandth of a single molecule be enough for a person? Or might a single molecule intoxicate a thousand people? And how long a chain on the alpha-position might be sufficient that, by merely writing down the structure on a piece of paper, you would get high? Maybe just conceiving the structure in your mind would do it. That is, after all, the way of homeopathy. Maybe it was just as well that this added two-carbon side-chain with lowered activity was already enough to disprove the doubling pattern. But by the time this non-activity had been learned, the alpha series had already been pushed out quite aways. The machinery of making the appropriate nitroalkane was straightforward, by reaction of the alkyl halide with nitrous acid, and separating the unwanted nitrite ester from the wanted nitroalkane by fractional distillation. The nitrostyrenes all formed reasonably although often in terrible yields, and reduced reasonably, and all formed crystalline picrates for isolation and crystalline hydrochloride salts for pharmacological manipulation. But since the first of these, AEM, was not active, there was no enthusiasm for tasting anything higher. This family was never published; why publish presumably inactive and thus uninteresting material? The Table presents the properties of the precursor nitrostyrenes, and the product picrate and hydrochloride salts, at least whatever information I can still find after thirty years: TABLE.

The color changed from a near-black to a light yellow. The mixture was filtered, the solids washed with acetone, and the solvent from the combined filtrate and washes removed under vacuum. The residue was suspended in acidified H2O, and extracted with 3x100 mL CH2Cl2. The pooled extracts were washed with 2x50 mL 5% NaOH, once with dilute HCl (which lightened the color of the extract) and then stripped of solvent under vacuum giving 12.4 g of an amber-colored oil. This was distilled at 125-137 deg C at 0.1 mm/Hg to yield 5.7 g of 3,5-dimethoxy-4-allyloxyphenylacetonitrile as a yellow oil. Anal. (C13H15NO3S) C,H. A suspension of 4.0 g LAH in 150 mL anhydrous THF under N2 was cooled to 0 deg C and vigorously stirred. There was added, dropwise, 2.8 mL 100% H2SO4, followed by 5.5 g 3,5-dimethoxy-4-allyloxyphenylacetonitrile in 10 mL anhydrous THF. The reaction mixture was stirred at 0 deg C for a few min, then brought to a reflux on the steam bath for 30 min. After cooling back to room temperature, there was added sufficient IPA to destroy the excess hydride, followed by sufficient 10% NaOH to form granular solids. These were removed by filtration, and washed with 20 mL IPA. The filtrate and washes were stripped of solvent under vacuum and the residue added to 100 mL dilute H2SO4. This was washed with 2x50 mL CH2Cl2, made basic with aqueous NaOH, and extracted with 2x75 mL CH2Cl2. These extracts were pooled, the solvent removed under vacuum, and the residue distilled at 110-120 deg C at 0.4 mm/Hg to give 4.9 g of a colorless oil. This was dissolved in 15 mL IPA, neutralized with concentrated HCl (55 drops required), and diluted with 50 mL Et2O. The product was removed by filtration, washed with Et2O, and air dried to give 4.9 g of 3,5-dimethoxy-4-allyloxyphenethylamine hydrochloride (AL) as white crystals. DOSAGE: 20 - 35 mg. DURATION: 8 - 12 h. QUALITATIVE COMMENTS: (with 24 mg) I first became aware of something in about 10 minutes, a pleasant increase in energy. By 20 minutes it was getting pronounced and was a nice, smooth development. During the next hour positive and negative feelings developed simultaneously. Following a suggestion, I ate a bit of food even though I had not been hungry, and to my surprise all the negative feelings dropped away. I felt free to join the others wherever they were at. I moved into the creative, free-flowing kind of repertoire which I dearly love, and found everything enormously funny. Much of the laughter was so deep that I felt it working through buried depressions inside me and freeing me. From this point on, the experience was most enjoyable. The experience was characterized by clear-headedness and an abundance of energy which kept on throughout the day and evening. At one point I went out back and strolled along to find a place to worship. I had a profound sense of the Presence and great love and gratitude for the place, the people, and the activities taking place. The come-down from the experience was very gradual and smooth. Food tasted wonderful. I went to bed late, and quite ready for bed, although the energy was still running. However, sleep was not long in coming. (with 24 mg) The onset was extremely gradual and graceful, with the first alert that one could really sense at about 50 minutes. This was succeeded by a slow gentle climb to the peak at one hour and fifteen minutes. The experience itself left all of the sensory modalities functional; speech was cogent and rather fluid. In fact, there was an unusual ease of free association. All throughout the session, the talk was high in spirits and somehow indicative of an inner excitement. Affect was entirely pleasant, but not exalting nor conducive to insight or to problem solving. There were no requirements for withdrawal into the self. The material seemed wholly social in nature. No visual, auditory or olfactory sharpening was in evidence. The plateau for this material seemed unusually long. I was unable to sleep for several hours, and took 25 mg Librium before sleep arrived. The next day was a lethargic and slow one, with the inner feeling that the effects had not worn off until the middle of the day following ingestion. (with 35 mg) I was a distinct +1 in 35 minutes and a +2 by the end of the hour. My head congestion in no way cleared up, absolving the material from having that particular virtue. The entire experience was somewhat dissociated Q I could not connect with my feelings. Although my mind remained clear, there was a hangover feeling at the end of the experiment. EXTENSIONS AND COMMENTARY: This compound was first explored in Prague by Leminger. He provided only the synthetic details and the statement that it was the most active compound that he had studied, with activity at 20 milligrams, with perceptual changes, color enhancement, and difficult dreams during sleep that night. Some effects persisted for more than 12 hours. Dosages above 35 milligrams remain unexplored. As AL is one of the most potent 3,4,5-trisubstituted phenethylamines yet described, and since the corresponding amphetamines are of yet greater potency, it would be a good guess that 4-allyloxy-3,5-dimethoxyamphetamine (3C-AL) would be an interesting compound to explore. It could be made from syringaldehyde in reaction with allyl iodide, followed by the formation of a nitrostyrene with nitroethane, followed by reduction with aluminum hydride. It is, as of the present time, both unsynthesized and unexplored. #3 ALEPH; DOT; PARA-DOT; 2,5-DIMETHOXY-4-METHYLTHIOAMPHETAMINE SYNTHESIS: A solution of 2.3 g 2,5-dimethoxy-4-(methylthio)benzaldehyde (see under 2C-T for its synthesis) in 7.5 mL nitroethane was treated with 0.45 g anhydrous ammonium acetate and heated on the steam bath for 6 h. The excess solvent/reagent was removed under vacuum leaving a mass of orange crystals as residue. These were ground up under 10 mL MeOH, col-lected by filtration, washed with a little MeOH, and air dried to provide 2.6 g crude 1-(2,5-dimethoxy-4-methylthiophenyl)-2-nitropropene. After recrystallization from 140 mL boiling MeOH, filtering and drying there was in hand 1.8 g of bright orange crystals with a mp of 137-138 deg C. Anal. (C12H15NO4S) C,H,N,S. A suspension of 1.4 g LAH in 10 mL anhydrous Et2O and 40 mL anhydrous THF was put under an inert atmosphere and, with good stirring, brought up to a gentle reflux. A solution of 1.8 g 1-(2,5-dimethoxy-4-methylthiophenyl)-2-nitropropene in 30 mL anhydrous THF was added dropwise at a rate that maintained the reflux. Heating and stirring were maintained for an additional 7 h, then the reaction mixture was allowed to return to room temperature. There was added 1.6 mL H2O (dissolved in a little THF), followed by 1.6 mL 15% NaOH, and finally another 4.8 mL H2O. Stirring was continued until all the curdy solids had turned white. The reaction mixture was filtered, and the filter cake washed with THF. The filtrate and the washings were combined, and the solvent removed under vacuum. The residue was 1.3 g of a colorless oil that solidified. Its mp of 90-93 deg C was improved slightly to 91-93 deg C with recrystallization from hexane. The product was dissolved in 25 mL warm IPA, neutralized with concentrated HCl (0.57 mL required) and then diluted with 100 mL anhydrous Et2O. After a moment's delay, the white crystalline product appeared. It was removed by filtration, washed with Et2O, and air dried to provide 1.2 g 2,5-dimethoxy-4-methylthioamphetamine hydrochloride (ALEPH) with a mp of 200-201 deg C. Recrystallization from IPA gave an analytical sample with a mp of 204-205 deg C. Anal. (C12H20ClNO2S) C,H; N: calcd, 5.04; found, 5.52. DOSAGE: 5 - 10 mg. DURATION: 6 - 8 h. QUALITATIVE COMMENTS: (with 5 mg) The initial hints of action were physical Q warming of first the legs, and then a comfortable warmth spread over the entire body. Intense intellectual stimulation, one that inspired the scribbling of some 14 pages of handwritten notes. Which is a pretty good record for an experience that is almost entirely non-verbal. The afterglow was benign and rich in empathy for everything. And by the sixth hour I was quite hungry. (with 10 mg) There was a rapid shift of frame of reference that made simple tasks such as reading and tuning the radio quite alien. I happened to catch the eyes of Pretty Baby, the cat, at the same moment she looked at me, and she turned and fled. I am able to interact with people on the telephone quite well but mechanical things, such as arranging flowers or alphabetizing names, are beyond me. Driving would be impossible. EXTENSIONS AND COMMENTARY: This specific compound is probably the first sulfur-containing phenethylamine to have been evaluated as a potentially active CNS stimulant or psychedelic. It was a complete, total, absolute unknown. The first trials were made at the sub-microgram level, specifically at 0.25 micrograms, at 11:30 AM on September 3, 1975. Part of this extreme precaution was due to the uniqueness of a new heteroatom in a phenethylamine system. But part was due to the strange manic excitement that occurred at the time of the isolation and characterizing of the final product in the laboratory. Although it was certainly all placebo response, I was jumpy and unable to stay in the lab for more than a few minutes at a time. Maybe dust in the air? Maybe some skin contact with the free base? Now, I know there was nothing, but the possibility of extraordinary potency was real, and I did indeed wash everything down anyway. In fact, it took a total of 18 trials to work the experimental dosage up to as much as a single milligram. In retrospect, overly cautious. But retrospection, as they say, is cheap. The 5 milligram experiment, briefly quoted from above, is the stuff of Chapter 14 of this book, important in that it gives an interesting example of some thought processes associated with psychedelic intoxication, ego-inflation, and what might be thought of as bits of mania. As is always the case with peak experiences that happen to be catalyzed by drugs, this extraordinary event could not be duplicated. At 7 milligrams there was an uneventful +1, and some 10 milligrams was needed to generate a full +3 experience. The first clue of the erratic nature of the Aleph family came from an independent assay by a colleague of mine, one who was very familiar with such states of consciousness, but for whom this was not a time for peak experiences. At 10 milligrams he told me that he had had only mild effects which he found relatively uninteresting. As it stands, ALEPH remains relatively unexplored. Its two positional isomers are entered here as ORTHO-DOT and META-DOT. Three higher homologues have been more thoroughly looked at, and the generic name ALEPH (the first letter of the Hebrew alphabet) was given this group on the basis that they might have extraordinary properties in common. But the real treasure came in the exploring of the 2-carbon homologues, the compounds that make up the 2C-T family. Here, there proved to be much less uncertainty as to reasonable dosages, and much more richness in the subjective nature of the experience. |
