実験手順
Prepared from 4'-bromomethyl-1,1'-biphenyl-2-nitrile (prepared by the method of M. Fisher, et al, U.S. Pat. No. 5,206,235) and 3(R)-t-butoxycarbonylamino-2,3,4,5-tetrahydro-1H-1-benzazepin-2-one (Step A) by the procedure described in Example 1, Step Q. 1H NMR (400 MHz, CDCl3): δ 1.39 (s, 9H), 1.90 (m, 1H), 2.40-2.60 (m, 3H), 4.28 (m, 1H), 4.94 (d, 15 Hz, 1H), 5.20 (d, 15 Hz, 1H), 5.43 (d, 7 Hz, 1H), 7.1-7.3 (m, 4H), 7.33 (d, 8 Hz, 2H), 7.35-7.50 (m, 4H), 7.60 (t, 8 Hz, 1H), 7.72 (d, 8 Hz, 1H). FAB-MS: calculated for C29H29N3 O3 467; found 468 (M+H, 15%), 368 (M-BOC, 100%).
