Ammonia → 4-tert-Butylcyclohexylamine

Participants

Reaction Steps

312 g of 4-tert-butylcyclohexanone in 500 ml of ammonia-saturated methanol were hydrogenated at 100° C. and 100 bar in the presence of 10 g of Raney nickel. The catalyst was filtered off, the mixture was concentrated, and the crude product was purified on a thin-layer evaporator (105°/0.5 mm). 303 g of colorless liquid were obtained. The product is an isomer mixture in which the cis-cyclohexylamine derivative prevails. ##STR11##
