Reaction Steps

To a solution of [(S)-3-Benzyloxy-2-(tert-butoxycarbonyl-methyl-amino)-propyl]-(2,2-difluoro-ethyl)-carbamic acid tert-butyl ester (2.42 g, 5.28 mmol) in MeOH (20 mL) and AcOH (2.0 mL) was added Pd/C (10%, 1.0 g). The reaction mixture was transferred to an autoclave and charged with hydrogen (50 psi). The mixture was stirred RT for 20 h and filtered. The filtrated was concentrated and the residue was purified on silica gel using a mixture of EtOAc and hexanes to give [(S)-2-(tert-Butoxycarbonyl-methyl-amino)-3-hydroxy-propyl]-(2,2-difluoro-ethyl)-carbamic acid tert-butylester (1.81 g, 93%). LRMS (M+Na+) m/z 391.2.
