Reaction Steps

The title compound was prepared by substituting (3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine from Step A of Example 33 for (3aS,4R,6aR)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine and substituting (R)-2-phenylbutanoic acid for (S)-2-phenylbutanoic acid in Step F of the procedure used to prepare Example 16: 1H NMR (500 MHz, CDCl3) δ ppm 7.38-7.21 (m, 10H), 5.29 (d, J=6.9, 1H), 4.04-3.90 (m, 1H), 3.65 (d, J=12.9, 1H), 3.52 (d, J=12.9, 1H), 3.15 (t, J=7.6, 1H), 2.68 (t, J=8.6, 1H), 2.64-2.48 (m, J=8.5, 3H), 2.30-2.22 (m, J=3.7, 8.3, 1.5H), 2.14 (ddd, J=7.4, 13.9, 19.9, 1.5H), 1.93 (dt, J=6.2, 12.5, 1H), 1.84-1.62 (m, J=7.6, 14.5, 20.6, 2H), 1.45-1.27 (m, 2H), 0.95-0.80 (m, 4H); MS (ESI+) m/z 363 (M+H)+.
