Reaction Steps
The title compound was prepared by substituting (S)-2-(isopropoxycarbonylamino)pentanoic acid from Step A of Example 263 for (S)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid and (3aR,4S,6aS)-2-(4-(trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine from Step A of Example 256 for (3aS,4R,6aR)-2-(3-(trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine in the procedure described in Example 266: 1H NMR (501 MHz, pyridine-d5) δ ppm 8.08 (d, J=8.2, 2H), 7.96 (d, J=4.8, 1H), 7.82 (d, J=8.3, 2H), 7.18 (d, J=4.5, 2H), 5.01 (hept, J=6.2, 1H), 4.45 (dd, J=14.0, 7.7, 1H), 4.11 (dt, J=13.0, 6.7, 1H), 3.67 (dd, J=10.2, 3.0, 1H), 3.30 (dd, J=10.2, 7.6, 1H), 3.16-3.07 (m, 2H), 2.57 (h, J=9.3, 2H), 1.99-1.85 (m, 2H), 1.86-1.72 (m, 2H), 1.58-1.50 (m, 1H), 1.45 (ddd, J=20.8, 11.7, 7.2, 2H), 1.26 (ddd, J=13.1, 10.9, 6.6, 1H), 1.19 (d, J=6.2, 3H), 1.16 (d, J=6.2, 3H), 0.84 (t, J=7.4, 3H); MS (ESI+) m/z 520 (M+H)+.
