Procedure

A solution of (1R,2S,5R)-methyl 2-((S)-3-(benzyloxycarbonylamino)-2-oxopyrrolidin-1-yl)-5-(tert-butylamino)-cyclohexanecarboxylate (2.42 g, 5.43 mmol) in methanol was treated with 600 mg of 10% Pd/C and hydrogenated at 55 psi of H2 in a Parr shaker overnight. The catalyst was filtered and the filtrate concentrated in vacuo to give 1.64 g of (1R,2S,5R)-methyl 2-((S)-3-amino-2-oxopyrrolidin-1-yl)-5-(tert-butylamino)-cyclohexanecarboxylate as a white solid. This was used without further purification. MS found: (M+H)+=312.32.
