Participants

Reaction Steps

The title compound was prepared by substituting (S)-2-(neopentylamino)pentanoic acid from Step A of Example 246 for N-(tert-butoxycarbonyl)-L-leucine and (3aS,4R,6aR)-2-(4-(trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine from Step A for (3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine in the procedure described in Example 221: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.09-8.14 (m, 3H), 7.88-7.91 (m, 2H), 4.20-4.26 (m, 1H), 3.88 (dd, J=9.9, 2.9 Hz, 1H), 3.13-3.21 (m, 3H), 2.98 (dd, J=9.6, 7.4 Hz, 1H), 2.49-2.64 (m, 2H), 2.38 (d, J=11.2 Hz, 1H), 2.33 (d, J=11.2 Hz, 1H), 1.91-1.99 (m, 1H), 1.76-1.90 (m, 2H), 1.66-1.95 (m, 1H), 1.62-1.71 (m, 1H), 1.41-1.58 (m, 3H), 1.33 (ddt, J=9.5, 13.0, 6.5 Hz, 1H), 0.92 (s, 9H), 0.86 (t, J=7.3 Hz, 3H); MS (ESI+) m/z 504 (M+H)+.
