Participants

Reaction Steps

The title compound was prepared by substituting (S)-4-methyl-2-(neopentylamino)pentanoic acid from Step A of Example 244 for N-(tert-butoxycarbonyl)-L-leucine and (3aR,4S,6aS)-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 (400 MHz, pyridine-d5) δ ppm 8.20-8.23 (m, 1H), 8.13-8.16 (m, 2H), 7.89-7.92 (m, 2H), 4.21-4.29 (m, 1H), 3.86 (dd, J=9.9, 2.8 Hz, 1H), 3.22-3.28 (m, 1H), 3.15-3.22 (m, 2H), 2.99 (dd, J=9.6, 7.0 Hz, 1H), 2.50-2.62 (m, 2H), 2.43-2.47 (m, 1H), 2.28-2.32 (m, 1H), 1.92-2.02 (m, 1H), 1.80-1.92 (m, 2H), 1.64-1.76 (m, 1H), 1.69 (ddd, J=13.5, 7.7, 5.8 Hz, 1H), 1.50-1.61 (m, 2H), 1.25-1.40 (m, 1H), 0.93 (d, J=6.8 Hz, 3H), 0.93 (s, 9H), 0.86 (d, J=6.5 Hz, 3H); MS (ESI+) m/z 518 (M+H)+.
