To a solution of benzyl (S)-1-((1S,2R,4R)-2-formamido-4-(isopropyl(methyl)amino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (50 mg, 0.116 mmol) in methanol (3 mL) was added 10% Pd/C (40 mg of 50% wet catalyst). The flask was evacuated and back-filled with hydrogen from a hydrogen balloon. The mixture was stirred at room temperature for 1 h and the catalyst was removed by filtration. The filtrate was concentrated in vacuo to provide N-((1R,2S,5R)-2-((S)-3-amino-2-oxopyrrolidin-1-yl)-5-(isopropyl(methyl)amino)cyclohexyl)formamide (35 mg, 100%) which was taken on to the next step without further purification. LC/MS found [M+H]+=297.
