N-Methylcyclohexylamine → HCID 20319113, compound

Participants

Reaction Steps

24 gm of N-methyl-cyclohexylamine were added to 23 gm of 2-acetylamino-5-tert.butyl-benzylbromide in 1.6 liters of carbon tetrachloride, and the mixture was refluxed for 1 hour. After cooling, the precipitated N-methyl-cyclohexylamine hydrobromide was filtered off, the filtrate was evaporated, and the crude product was purified chromatographically on silicagel with ethyl acetate. The corresponding fractions were combined and evaporated, and the 2-acetylamino-5-tert.butyl-N-cyclohexyl-N-methyl-benzylamine thus obtained was recrystallized from petroleum ether, whereupon it had a melting point of 111°-112.5°C.
