실험 절차

A mixture of benzyl 3-[(tert-butoxycarbonyl)amino]-1-piperidinecarboxylate (2.25 g, 6.73 mmol) and 10% Pd/C (0.229 g) in EtOH (20 mL) was stirred at room temperature under a hydrogen atmosphere (1 atm) for 14 hrs. The catalyst was removed by filtration through Celite®, and the filtrate was concentrated under reduced pressure to give tert-butyl 3-piperidinylcarbamate as a solid (1.22 g, yield; 91%).
