N-Methylcyclohexylamine → HCID 20318945, compound

Participants

Reaction Steps

48 gm of N-methyl-cyclohexylamine were added to 56 gm of 4-acetylamino-3-tert.butyl-benzyl bromide in 500 ml of chloroform, and the mixture was refluxed for 1.5 hours. Subsequently, the reaction mixture was extracted three times with water, and the organic phase was evaporated. The residue was purified column-chromatography on silicagel with chloroform/methanol (5:1), and 4-acetylamino-3-tert.butyl-N-cyclohexyl-N-methyl-benzylamine hydrochloride, m.p. 240°-243° C (decomp.), was crystallized from a solution of the purified base in absolute ethanol/ether by addition of absolute ethanolic hydrochloric acid.
