SYNTHESIS: A solution of 0.4 g 1-(2,5-dimethoxy-4-methylphenyl)-1-methoxy-2-nitroethane (see preparation in the recipe for 2O. After washing the aqueous phase with 3×75 mL CH2Cl2, the mixture was made basic with 25% NaOH, and extracted with 3×50 mL CH2Cl2. Removal of the solvent and distillation of the residue at 130–140 °C 0.25 mm/Hg gave an oil that, on dissolving in IPA, neutralization with concentrated HCl, and the addition of anhydrous Et2O, gave beautiful white crystals of 2,5-dimethoxy-β-hydroxy-4-methylphenethylamine hydrochloride (BOHD). The yield was 0.2 g, and the mp was 180–181 °C. The infrared spectrum was that of an amine salt with a strong OH group present. Anal. (C11H18ClNO3) C,H.
DOSAGE: greater than 50 mg.
QUALITATIVE COMMENTS: (with 50 mg) “At about the two hour point, there was a precipitous drop of blood pressure (from 120/72 to 84/68) although the pulse stayed steady at 60. This trend had been apparent in earlier trials, and was being watched carefully. No further tests are planned.”
EXTENSIONS AND COMMENTARY: The usual method of making β-ethanolamine such as this is through the reduction of the cyanohydrin of the corresponding benzaldehyde and, in fact, that method is described in the recipe for
Why the potent cardiovascular effect seen by this compound? There are a couple of points that might argue for some adrenolytic toxicity. This material is a β-ethanolamine and, with maybe one or two exceptions, clinically used beta-receptor blockers are β-ethanolamines. In fact, a few of these so-called beta-blockers actually have two methoxy groups on the aromatic rings, also a property of BOHD. The antidiabetic drug
The code-naming procedure used here (and elsewhere here in Book II) is: (1) to use “BO” as the alert to there being an oxygen on the benzyl carbon of a phenethylamine (it is a benzyl alcohol); (2) if there is just one more letter (a third and last letter) it will identify the 2C-X parent from which it has been derived [“B” comes from
Complex, yes. But both systems are completely straightforward, and flexible for future creations. A few additional examples of similar β-ethanolamines are scattered throughout Book II and they have, in general, proved to be uninteresting, at least as potential psychedelic compounds.
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 history 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.
