Procedure

Prepared from 3-benzyloxycarbonylamino-3-methylbutanoic acid (Step C) and 3(R)-amino-2,3,4,5-tetrahydro-1H-benzazepin-2-one (Example 1, Step E) substituting benzotriazol-1-yloxytripyrrolidinophosphonium hexafluorophosphate for benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate according to the procedure described in Example 1, Step I. 1H NMR (200 MHz, CDCl3): δ 1.37 (s, 6H), 1.82 (m, 1H), 2.45-2.75 (m, 4H), 2.86 (m, 1H), 4.49 (m, 1H), 5.05 (dd; 10, 6 Hz; 2H), 5.55 (s, 1H), 6.73 (s, 1H), 6.96 (d, 4 Hz, 1H), 7.10-7.40 (m, 8H) and 8.68 (s, 1H). FAB-MS: calculated for C23H27N3O4 409; found 410 (M+H, 100%).
