- I can't believe no one caught my special atomic modification of Nitrogen
- that takes 4 bonds! What, are you people asleep out there??? Anyway, a
- couple of modifications, slightly revised question/answers and a CORRECTED
- ascii drawing are in this rev. This makes the FAQ reasonably accurate but
- still not what I'd call a definitive source by any means. Thanks to all who
- have sent comments thus far and let me know successes and failures
- (anonymously!).

- The 4-Methylaminorex pseudo-FAQ (beta)
- ---------------------------------------------------------------------
-
- 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.
-
- *STANDARD DISCLAIMER* - This is for informational purposes only. It
- is being produced in order to illustrate the
- novel structure and effects of the aryl-
- oxazolines. 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.

- 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 [1] (ie - 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
- ---------------------------------------
-
- Reagents
- --------
- Phenylpropanolamine HCl
- Methanol
- Cyanogen Bromide
- Sodium Acetate
- Sodium Carbonate
- Water
- Benzene (or similar)
- Ether
-
-
- Extraction of Phenylpropanolamine from OTC preparations
- -------------------------------------------------------
- 1) 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.
-
- 2) 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.
-
- 3) 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
- later on.
-
-
- Forming the Oxazoline Ring
- --------------------------
- The ideal ratio of all the reagents is as follows [2]:
-
- 1.0 Mole Phenylpropanolamine (MW: 151.2)
- 1.1 Moles Cyanogen Bromide (MW: 105.93)
- 3.0 Moles of Sodium Acetate (MW: 82.04)
-
- 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
- mine.
-
- 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.
-
- 1) Dissolve 15g (.142M) of Cyanogen Bromide in 50mL of Methanol at 0C.
-
- 2) 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.
-
- 3) Add the Cyanogen Bromide solution to the flask though the addition
- funnel over a period of 15 minutes with stirring.
-
- 4) React for an additional 45 minutes at 0C.
-
- 5) Evaporate solvents at reduced pressure and with gentle water bath
- heat (50C tops) - do not attempt to recover!
-
- 6) Dissolve the oily residue in water and then add saturated Sodium
- Carbonate solution until a white solid precipitates.
-
- 7) Filter this cake of white solid on the Buchner, then wash twice
- with ice cold water and dry in a vacuum dessicator.
-
- 8) Recrystallize the crude dried product from Benzene to yield ~63%.
-
- 9) *OPTIONAL* - Form the hydrochloride salt by bubbling HCl gas though
- the Benzene until white crystals fall out or shaking with 5% HCl
- and evaporating the water off.
