benzyl (S)-1-((1S,2R,4R)-2-acetamido-4-(tert-butylamino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate → N-((1R,2S,5R)-2-((S)-3-amino-2-oxopyrrolidin-1-yl)-5-(tert-butylamino)cyclohexyl)acetamide

Participants

Reaction Steps

To a solution of benzyl (S)-1-((1S,2R,4R)-2-acetamido-4-(tert-butylamino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (22 mg, 0.05 mmol) in methanol (2 mL) was added Pd(OH)2 (20 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-(tert-butylamino)cyclohexyl)acetamide (13 mg, 85%). LC/MS found [M+H]+=311.
