Procedure

A solution of tert-butyl (1R,3R,4S)-4-((S)-3-benzyloxycarbonylamino-2-oxopyrrolidin-1-yl)-3-(methylsulfonylmethyl)cyclohexylcarbamate (835 mg) in MeOH (5 mL) was charged with 10% Pd/C, Degussa (800 mg). The reaction flask was evacuated and then back-filled with hydrogen; this was repeated three more times. The reaction was stirred under 1 atm of H2 for 2 h and then filtered and concentrated to afford tert-butyl (1R,3R,4S)-4-((S)-3-amino-2-oxopyrrolidin-1-yl)-3-(methylsulfonylmethyl)cyclohexylcarbamate (566 mg). MS found: (M+H)+=390.3.
