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 (3aR,4S,6aS)-2-(4-(trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine from Step A of Example 256 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 8.37-8.38 (bs, 1H), 8.13-8.18 (m, 3H), 7.89-7.91 (m, 2H), 4.21-4.28 (m, 1H), 3.86 (dd, J=9.9, 2.9 Hz, 1H), 3.16-3.22 (m, 3H), 2.98 (dd, J=9.6, 7.3 Hz, 1H), 2.47-2.61 (m, 2H), 2.41 (d, J=11.2 Hz, 1H), 2.32 (d, J=11.2 Hz, 1H), 1.93-2.00 (m, 1H), 1.78-1.88 (m, 2H), 1.63-1.70 (m, 1H), 1.41-1.58 (m, 3H), 1.28-1.36 (m, 1H), 0.93 (s, 9H), 0.86 (t, J=7.3 Hz, 3H); MS (ESI+) m/z 504 (M+H)+.
