실험 절차

The title compound was prepared by substituting N-(tert-butoxycarbonyl)-N-methyl-L-leucine for N-(tert-butoxycarbonyl)-L-leucine and (3aS,4S,6aR)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine from Step C of Example 14 for (3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine in the procedure described in Example 221: 1H NMR (501 MHz, pyridine-d5, temperature 90° C.) δ ppm 7.44-7.49 (m, 2H), 7.36-7.40 (m, 2H), 7.32-7.39 (m, 1H), 7.27 (t, J=7.4 Hz, 1H), 4.82-4.89 (m, 1H), 4.37-4.43 (m, 1H), 3.63 (d, J=13.2 Hz, 1H), 3.50 (d, J=13.0 Hz, 1H), 2.94 (s, 3H), 2.73 (dd, J=9.7, 1.8 Hz, 1H), 2.64-2.70 (m, 1H), 2.44-2.47 (m, 2H), 2.22-2.28 (m, 1H), 2.15-2.19 (m, 1H), 1.88 (ddd, J=14.1, 8.2, 6.0 Hz, 1H), 1.64-1.81 (m, 3H), 1.55-1.65 (m, 2H), 1.50 (s, 9H), 1.28-1.38 (m, 1H), 0.90-0.93 (m, 6H); MS (ESI+) m/z 444 (M+H)+.
