Dl-a-Methylphenethylamine

Two mols, for example, 270 grams, of racemic a-methylphenethylamine base are reacted with one mol (150 grams) of d-tartaric acid, thereby forming dl-a-methylphenethylamine d-tartrate, a neutral salt. The neutral salt thus obtained is fully dissolved by the addition of sufficient, say about 1 liter, of absolute ethanol, and heating to about the boiling point. The solution is then allowed to cool to room temperature with occasional stirring to effect crystallization. The crystals are filtered off and will be found to contain a preponderance of the levo enantiomorph.

Of a series of 35 a- and of S-alkyl substituted phenethylamines being investigated for CNS effects, two compounds, B-1268 (Via) and B-1279 (VIb) were reported to be comparable to chlorphentermine in reducing food and bouillon consumption in rats. 3 dl-p-Chloro-N-(cyclopropy]. methyl)-or-methylphenethylamine A-3196O (VIl) has been compared to methamphetamine and diethylpropion (VIll) in man. It was found to have comparable activity in respect to appetite suppression and CNS stimulation to methamphetamine and diethylpropion.
