3-Benzyloxycarbonylamino-3-(2-hydroxy-1-methylethyl)piperidine-1-carboxylic acid tert-butyl ester → 3-Amino-3-(2-hydroxy-1-methylethyl)piperidine-1-carboxylic acid tert-butyl ester

Participants

Reaction Steps

To a solution of an optically-active compound of 3-benzyloxycarbonylamino-3-(2-hydroxy-1-methylethyl)piperidine-1-carboxylic acid tert-butyl ester (374 mg) in methanol (6 ml) was added 10% palladium carbon (38 mg), and the mixture was hydrogenated at room temperature under ordinary pressure for 14 hours. The mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure to give the titled compound (269 mg).
