実験手順
10% Pd/C (0.20 gm, 0.19 mmol) was added to a solution of benzyl 3-((1R,2R)-2-(tert-butoxycarbonylamino)cyclohexylamino)piperidine-1-carboxylate, (1.73 gm, 4.01 mmol) in MeOH (14.6 mL) and AcOH (1.46 mL). A H2 atmosphere was then introduced via balloon. After 1 h the reaction mixture was filtered through Celite. The catalyst was rinsed with MeOH and the filtrate was concentrated. The residue was partitioned between EtOAc and sat. NaHCO3. The aqueous phase was isolated and extracted with EtOAc. All organic phases were combined, washed with saturated aqueous NaCl, dried over MgSO4, filtered and concentrated to give the product tert-butyl (1R,2R)-2-(piperidin-3-ylamino)cyclohexylcarbamate (1.02 gm, 3.43 mmol, 86% yield) as a white foam. Anal. Calcd. for C16H31N3O2 m/z 297.2, found: 298.2 (M+H)+. Crude product was used without purification.
