Reaction Steps

Prepared from 3-benzyloxycarbonylamino-3-methyl-N-[2,3,4,5-tetrahydro-2-oxo-1H-1-benzazepin-3-yl ]-butanamide (Example 51, Step A) and methyl 4'-bromomethyl-1,1'-biphenyl-2-carboxylate (prepared by the method of D. J. Carinie et al, EPO publication 324,377) by the procedure described in Example 1, Step K. 1H NMR (300 MHz, CDCl3): 1.37 (s,3H), 1.39 (s,3H), 1.75 (m,1H), 2.3-2.6 (m,5H), 3.52 (s,3H), 4.50 (m,1H), 4.80 (d,14Hz,1H), 5.06 (s,2H), 5.34 (d,14Hz,1H), 5.65 (s,1H), 6.72 (d,7Hz,1H), 7.1-7.4 (m,15H), 7.48 (dt;2,8Hz;1H), 7.78 (dd;2,8Hz;1H).
