To a solution of N-benzyloxycarbonylamine 90 (330 mg, 0.79 mmol) in MeOH (40 mL) at room temperature, Pd—C (10% wt, 100 mg, 0.09 mmol) was added. The mixture was purged with a stream of dry Ar, and then H2. The reaction was stirred overnight under a H2 atmosphere (1 atm). The catalyst was filtered off through a 0.45 μm teflon filter in polypropylene housing, washing the filter with MeOH (50 mL) and the solvent was evaporated in vacuo. The crude was purified by column chromatography on silica (90:10 CH2Cl2/MeOH to 100% MeOH) to obtain aminoalcohol 91 as a white solid (200 mg, 89% yield).
