A solution of benzyl (S)-1-((1S,2R,4R)-2-amino-4-(tert-butylamino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (22 mg, 0.055 mmol) in dichloromethane (2 mL) was charged sequentially with triethylamine (11.1 mg, 2 eq) and acetic anhydride (6.1 mg, 1.1 eq). The reaction was stirred for 1.5 h at room temperature, diluted with dichloromethane (50 mL) and washed with saturated NaHCO3 (20 mL). The organic phase was dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to give benzyl (S)-1-((1S,2R,4R)-2-acetamido-4-(tert-butylamino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (22 mg, 90%). LC/MS found [M+H]=445.
