Book II of PiHKAL: A Chemical Love Story. Alexander & Ann Shulgin #25: 3C-E
SYNTHESIS: A solution of 3.6 g syringaldehyde (3,5-dimethoxy-4- hydroxybenzaldehyde) in 50 mL MeOH was combined with a solution of 3.7 g 85% KOH in 75 mL warm MeOH. This clear solution suddenly set up to crystals of the potassium salt, too thick to stir satisfactorily. To this suspension there was added 7.4 g ethyl iodide (a large excess) and the mixture was held at reflux temperature with a heating mantle. The solids eventually loosened and redissolved, giving a clear amber-colored smooth-boiling solution. Refluxing was maintained for 2 days, then all volatiles were removed under vacuum. The residue was dissolved in 400 mL H2O, made strongly basic with 25% NaOH, and extracted with 4×100 mL CH2Cl2. The pooled extracts were washed with saturated brine, and the solvent removed under vacuum to give 3.3 g of a pale amber oil which set up as crystals of 3,5-dimethoxy-4-ethoxybenzaldehyde with a mp of 47–48 °C. A small sample recrystallized from methanol had a mp of 48–49 °C.
A solution of 3.3 g 3,5-dimethoxy-4-ethoxybenzaldehyde in 25 mL nitroethane was treated with 0.5 g anhydrous ammonium acetate and heated on the steam bath for 36 h. The solvent/reagent was removed under vacuum giving a thick yellow-orange oil that was dissolved in two volumes hot MeOH. As this cooled, crystals appeared spontaneously, and after cooling in ice for a short time, these were removed by filtration and washed sparingly with cold MeOH, Air drying to constant weight provided 2.2 g 1-(3,5-dimethoxy-4-ethoxyphenyl)-2-nitropropene with a mp of 84–85 °C. The mother liquors, on standing overnight, deposited large chunks of crystalline material which was isolated by decantation, ground up under a small amount of methanol, then recrystallized from 60% EtOH. A second crop of 0.7 g of the nitrostyrene was thus obtained, as canary-yellow crystals with a mp of 83–85 °C.
A solution of 2.7 g 1-(3,5-dimethoxy-4-ethoxyphenyl)-2-nitropropene in 20 mL anhydrous THF was added to a suspension of 2.0 g LAH in 150 mL warm THF. The mixture was held at reflux for 48 h. After stirring at room temperature for another 48 h, the excess hydride was destroyed by the addition of 2.0 mL H2O in 10 mL THF, followed by 2.0 mL 15% NaOH and then an additional 6.0 mL H2O. The inorganic salts were removed by filtration, and the filter cake washed with THF. The combined mother liquor and washings were stripped of solvent under vacuum leaving a yellow oil with some inorganic salts still in it. This was dissolved in 300 mL CH2Cl2, washed with dilute NaOH, and extracted with 3×150 mL 1 N HCl. The pooled extracts were washed once with CH2Cl2 made basic with 25% NaOH, and extracted with 3×100 mL CH2Cl2. The combined organics were washed with saturated brine, and the solvent removed under vacuum to yield about 2 mL of a colorless oil. This was dissolved in 10 mL IPA, neutralized with concentrated HCl (10 drops were required), and diluted with 125 mL anhydrous Et2O. The slight cloudiness gradually became the formation of fine white crystals. After standing at room temperature for 2 h, these were removed, Et2O washed, and air dried. There was thus obtained 1.9 g of 3,5-dimethoxy-4-ethoxyamphetamine hydrochloride (3C-E) as brilliant white crystals.
DOSAGE: 30–60 mg.
DURATION: 8–12 h.
QUALITATIVE COMMENTS: (with 40 mg) “It developed into a strange and indefinable something. It is unworldly. I am very much in control, but with an undertone of unreality that is a little reminiscent of high doses of
(with 60 mg) “Visuals very strong, insistent. Body discomfort remained very heavy for first hour. Sense of implacable imposition of something toxic for a while. I felt at the mercy of uncomfortable physical effects—faint or pre-nausea, heavy feeling of tremor (although tremor actually relatively light) and general dis-ease, un-ease, non-ease. Kept lying down so as to be as comfortable as possible. Fantasy began to be quite strong. At first, no eyes closed images, and certainly anti-erotic. 2nd hour on, bright colors, distinct shapes—jewel-like—with eyes closed. Suddenly it became clearly not anti-erotic. That was the end of my bad place, and I shot immediately up to a +++. Complex fantasy which takes over—hard to know what is real, what is fantasy. Continual erotic. Image of glass-walled apartment building in mid-desert. Exquisite sensitivity. Down by ? midnight. Next morning, faint flickering lights on looking out windows.”
EXTENSIONS AND COMMENTARY: This is an interesting closing of the circle. Although
About PiHKAL • info
This version of Book II of PiHKAL is based on the Erowid online version, originally transcribed by Simson Garfinkle and converted into HTML by Lamont Granquist. I drew also on “Tyrone Slothrop’s” (Unfinished) Review of PIHKAL to enumerate the many analogues mentioned in PiHKAL but not described at length. Many, many others have since been added.
I have tried here to expunge any artifacts introduced by the earlier transcriptions and restore the typographic niceties found in the printed edition. I’ve also made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The errata and changes page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”

PiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of phenethylamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of PiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
