実験手順
A solution of {(3S)-1-[(1S,2R,4R)-4-tert-butoxycarbonylamino-2-propyl-cyclohexyl]-2-oxo-pyrrolidin-3-yl}-carbamic acid benzyl ester (185 mg, 0.54 mmol) in MeOH (8 mL) was charged with 5% Pd/C, Degussa (180 mg). The reaction flask was evacuated and then back-filled with hydrogen; this was repeated three more times. The reaction was stirred under 1 atm of H2 for 12 h and then filtered and concentrated in vacuo to afford (1R,3R,4S)-{4-[(3S)-3-amino-2-oxo-pyrrolidin-1-yl]-3-propyl-cyclohexyl}-carbamic acid tert-butyl ester. MS found: (M+H)+=340.3.
