The 4-Methylaminorex pseudo-FAQ
Due to strangely increased demand for 4-Methylaminorex "recipes" that
I have received by mail, I decided to compile a short document with
the cognate preparation of this interesting compound. This may become
a full-fledged FAQ in the future, depending on user response and
outside input donated where this will undoubtedly be deficient.
||This is for informational purposes only. It is being produced in order
to illustrate the novel structure and effects of the aryloxazolines.
Use this information at your own risk, I cannot be held responsible
for what you do with it, etc... and so on.
Q1. What is Ice?
A1. Ice is a potent norepinephrine modulator, increasing it's effect.
It has a characteristic look and feel, like white opaque ice,
hence the name. Ice is currently a Schedule I drug as designated
by the DEA (Drug Enforcement Agency) which means it is felt to
have no medical use whatsoever. It was originally researched for
appetite suppressant ability, but never pursued, probably because
it's too much fun.
Q2. Can Ice be made from amphetamine/methamphetamine?
A2. It is technically possible, but requires some backwards
motions to get back to a sec. alcohol. At least one individual, in a
personal communication to me, indicated that "they knew of someone
who could convert crank [methamphetamine] into ice by washing it
with something." This is not possible.
Q3. What kind of chemical is it?
A3. In drug parlance, which is notoriously Non-IUPAC compliant, Ice
is synonymous with "Euphoria" (U4Euh), 4-Methylaminorex, or,
chemically speaking: dl-cis-2-amino-4-methyl-5-phenyl-2-oxazoline.
This is a tongue twister of a name, so I will explain and
illustrate it with a cheap floozie of an ascii drawing.
// \____ _____ ____CH3

The numbering starts at the heterocyclic Oxygen and goes counter-clockwise.
So the amine is at the 2 position, the methyl is at the
4 position, a phenyl ring is tacked on at the 5 position. Also, the
2-oxazoline part is often merely called oxazoline, as the double
bond to the heterocyclic Nitrogen is implied.
It is interesting to note that all of the stereoisomers of 4-MAR
are centrally active  (i.e. - it is not stereospecific in action).
Q4. What does Ice do?
A4. The document at Hyperreal.com describing the effects of Euphoria
would be a good place to start. Anecdotally, it is said to help
concentration and thinking - a sort of "make-you-smarter" drug,
with a minor speed-like component to it. Time of action is around
4-6 hours. Dosage varies but a good start is 20mg for a 150lb
individual. It is smoked as the free base or the hydrochloride
salt - both have relatively low melting points.
Cognate Preparation of 4-Methylaminorex
- Phenylpropanolamine HCl
- Cyanogen Bromide
- Sodium Acetate
- Sodium Carbonate
- Benzene (or similar)
Extraction of Phenylpropanolamine from OTC preparations
- Extract Phenylpropanolamine HCl (PPA) from OTC diet pills by
crushing and dissolving in 10mL methanol per gram of PPA. Decant
solution onto the Buchner funnel and repeat with 2 more volumes
of methanol. Use methanol instead of water because it has less
tendency to form a colloid with any cellulosic binders present
which would otherwise severely clog the filter paper.
- Distill off most of the methanol then add cold water to dissolve
all of the PPA solids. Basify to approximately pH 9 with 10%
Sodium Carbonate or Sodium Hydroxide solution. Extract out PPA
base using 3 volumes of ether of approximately 1/3 the volume
of water. The methanol will follow into the ether as well, but
very little of the formed salt will.
- Distill off ether/methanol for later recovery of the solvents and
weigh the amount of solid PPA base, mp 101C. The amount you process
here determines, obviously, the amounts of everything else to use
Forming the Oxazoline Ring
The ideal ratio of all the reagents is as follows :
The Sodium Acetate may be prepared by carefully adding an equinormal
amount of Sodium Hydroxide to glacial Acetic Acid and drying the
resultant salt at 120C for 15 minutes.
The preparation of Cyanogen Bromide is covered in another document of
This compound should only be prepared in an area of adequate
ventillation. A full covering fume hood is ideal (geez - make one,
I did) or outside with the wind blowing away from you. Cyanogen
Bromide acts on cytochrome oxidase just like any other cyanide and
will kill you quite effectively. Also, it has been known to decompose
spontaneously when impure.
- Dissolve 15g (.142M) of Cyanogen Bromide in 50mL of Methanol at 0C.
- Dissolve 19.5g (.129M) of Phenylpropanolamine and 31.8g (.387M) of
Sodium Acetate in 300mL of Methanol at 0C. Place this in a round
bottom flask equipped with a stirrer magnet and addition funnel.
- Add the Cyanogen Bromide solution to the flask though the addition
funnel over a period of 15 minutes with stirring.
- React for an additional 45 minutes at 0C.
- Evaporate solvents at reduced pressure and with gentle water bath
heat (50C tops) - do not attempt to recover!
- Dissolve the oily residue in water and then add saturated Sodium
Carbonate solution until a white solid precipitates.
- Filter this cake of white solid on the Buchner, then wash twice
with ice cold water and dry in a vacuum dessicator.
- Recrystallize the crude dried product from Benzene to yield ~63%.
- OPTIONAL - Form the hydrochloride salt by bubbling HCl gas
through the Benzene until white crystals fall out or shaking with 5%
HCl and evaporating the water off.
