Procedure

Prepared from 2-benzyloxycarbonylamino-2-methyl-N-[2,3,4,5-tetrahydro-2-oxo-1-[[2'-(aminomethyl)[1,1'-biphenyl]-4-yl]-methyl]-1H-benzazepin-3(R)-yl]propanamide, trifluoroacetate (Example 36, Step A) and ethyl isocyanate according to the procedure described in Example 37, Step A. 1H NMR (200 MHz, CD3OD): δ 1.03 (t, 7 Hz, 3H), 1.39 (s, 6H), 1.82 (m, 1H), 2.18-2.58 (m, 3H), 3.07 (q, 2H), 4.12 (s, 2H), 4.32 (m, 1H), 4.87 (d, 15 Hz, 1H), 5.00 (s, 2H), 5.31 (d, 15 Hz, 1H), 7.08-7.40 (m, 17H). FAB-MS: calculated for C39H43N5O5 661; found 662 (M+H, 100%).
