(S)-2-Phenylbutyric acid → (2S)-N-[(3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-yl]-2-(4-isobutylphenyl)propanamide

Participants

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 (S)-2-(4-isobutylphenyl)propanoic acid for (S)-2-phenylbutanoic acid in Step F of the procedure used to prepare Example 16: 1H NMR (400 MHz, CDCl3) δ ppm 7.28 (d, J=4.4, 3H), 7.25-7.18 (m, 1H), 7.15 (dd, J=2.3, 8.2, 2H), 7.09 (dd, J=1.8, 8.2, 2H), 5.17 (d, J=7.2, 1H), 4.03-3.89 (m, 1H), 3.58 (d, J=13.0, 1H), 3.51-3.41 (m, 2H), 2.55-2.48 (m, 3H), 2.45 (d, J=7.2, 2H), 2.39 (dd, J=7.3, 9.0, 1H), 2.27-2.20 (m, 1H), 2.19-2.06 (m, 1H), 2.05-1.91 (m, 1H), 1.85 (dt, J=6.8, 13.5, 1H), 1.72-1.61 (m, 2H), 1.48 (d, J=7.2, 3H), 1.44-1.28 (m, 2H), 0.89 (d, J=6.6, 6H); MS (ESI+) m/z 405 (M+H)+.
