Procedure
To a solution of an optically-active compound of 3-benzyloxycarbonylamino-3-(2-hydroxyethyl)piperidine-1-carboxylic acid tert-butyl ester (27.2 g) in methanol (544 ml) was added 10% palladium carbon (2.7 g), and the mixture was hydrogenated under ordinary pressure for 5 hours. The mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure to give the titled compound (17.2 g).
