실험 절차

To a solution of 1-(1-benzyloxycarbonyl-4-piperidinylmethyl)-4-(t-butoxycarbonylamino)piperidine (5.6 g) in ethanol (100 ml) is added 5% palladium-on-carbon (0.6 g), and the mixture is hydrogenated at 30° C. under atmospheric pressure. After a theoretical amount of hydrogen is consumed, the catalyst is removed by filtration, and the ethanol in the filtrate is evaporated under reduced pressure to give crude 4-(t-butoxycarbonylamino)-1-(4-piperidinylmethyl)piperidine (4.13 g).
