3,5-Dimethylaniline → 3,5-diMethyl-cyclohexylaMine

Participants

Reaction Steps

N-cis, cis-3,5-Dimethylcyclohexyl-N-cyclopentyl amine is synthesized as shown in Scheme M. 3,5-Dimethylcyclohexyl amine is synthesized by catalytic hydrogenation of 3,5-dimethyl aniline for 7 to 24 hours. A suitable catalyst is 5% ruthenium on carbon. Hydrogenation pressure may change from 500 to 1500 psi and temperatures may range from 80° to 150°. N-cis cis-3,5-Dimethylcyclohexyl-N-cyclopentyl amine is formed by reductive amination of cyclpentanone with 3,5-dimethylcyclohexyl amine. The reductive amination may be carried out by hydrogenation using palladium on carbon as catalyst at pressures ranging from 15 to 90 psi. The temperature may range from room temperature to 50°. The reaction time is from 7 to 48 hours.
