Reaction Steps
Prepared from 3-amino-3-methyl-N-[2,3,4,5-tetrahydro-2-oxo-1H-1-benzazepin-3(R)-yl]-butanamide, trifluoroacetate (Example 107, Step C) and (R)-2-benzyloxypropanol (prepared from ethyl-D-lactate according to the procedure of Hanessian and Kloss, Tetrahedron Lett. 1985, 26, 1261-1264.) by the procedure described in Example 86, Step A. 1H NMR (200 MHz,CD3OD): 1.31 (d,6 Hz,3H), 1.4 (s,3H), 1.43 (s,3H), 2.17 (m,1H), 2.30 (m,1H), 2.6-3.1 (m,5H), 3.22 (dd;3,12 Hz;1H), 3.86 (m,1H), 4.48 (dd;7,12 Hz;1H), 4.50 (d,12 Hz,1H), 4.70 (d,12 Hz,1H), 7.11 (d,8 Hz,1H), 7.15-7.45 (m,8H). FAB-MS: calculated for C25H33N3O3 423; found 424 (M+H, 100%).
