Reaction Steps

N-((3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-yl)-2,2-bis(4-fluorophenyl)acetamide (150 mg, 0.336 mmol) from Example 228 and ethanol (20 ml) were added to 20% Pd(OH)2 on carbon, wet (30.0 mg, 0.214 mmol) in a 50 mL pressure bottle and stirred for 2 hours at under 30 psi hydrogen at 50° C. The mixture was filtered and the solvent removed in vacuo to give 2,2-bis(4-fluorophenyl)-N-[(3aR,4S,6aS)-octahydrocyclopenta[c]pyrrol-4-yl]acetamide: 1H NMR (500 MHz, pyridine-d5) δ ppm 9.09 (d, J=7.1, 1H), 7.60-7.55 (m, 4H), 7.13 (q, J=8.2, 4H), 5.26 (s, 1H), 4.36-4.27 (m, 1H), 3.06 (dd, J=10.9, 2.7, 1H), 2.92 (dd, J=10.9, 7.0, 1H), 2.81 (dd, J=10.7, 7.0, 1H), 2.59 (dd, J=10.8, 2.8, 1H), 2.52-2.41 (m, 2H), 2.33-2.25 (m, 1H), 2.06-1.96 (m, 1H), 1.83 (td, J=12.7, 6.9, 1H), 1.65-1.52 (m, 1H), 1.26 (ddt, J=12.3, 8.7, 6.1, 1H); MS (ESI+) m/z 357 (M+H)+.
