Reaction Steps

Example 12bh, Step 1: A solution of (1R,2S,5S)-methyl 2-((S)-3-(benzyloxycarbonylamino)-2-oxopyrrolidin-1-yl)-5-(tert-butylamino)cyclohexanecarboxylate (200 mg, 0.4 mmol, obtained from Example 12b, Step 6 above), in methanol was treated with 60 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 130 mg of (1R,2S,5S)-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)+=312.3.
