t-Butyl beta-[4-(benzyloxycarbonylamino)cyclohexyl]acrylate → t-Butyl 3-(4-aminocyclohexyl)propionate

Participants

Reaction Steps

t-Butyl β-[4-(benzyloxycarbonylamino)cyclohexyl]acrylate (7.00 g, 19.5 mmol) was dissolved in methanol (200 ml) and 10% palladium-carbon (700 mg) was added. The mixture was stirred at room temperature for 24 hours under a hydrogen atmosphere. The reaction mixture was filtrated and low boiling matters were distilled away from the filtrate under reduced pressure. The residue was washed with a mixed solution of n-hexane and ethyl acetate to give 3.78 g of t-butyl 3-(4-aminocyclohexyl)propionate as a colorless solid (85%).
