Procedure

To a solution of 8.57 g (13.7 mmol) of 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, hydrochloride (Step I) in 75 mL of dry methylene chloride under nitrogen atmosphere was added 2.28 mL (16.4 mmol) of triethylamine followed by 0.89 mL (15 mmol) of methyl isocyanate. After stirring at room temperature for 45 minutes the solvent was removed under vacuum. The resulting material was dissolved in methylene chloride and purified by flash column chromatography on silica gel eluting with ethyl acetateethanol (96:4) to afford 7.73 g (87%) of product as a white foam. 1H NMR (200 MHz, CD3OD): δ 1.39 (s, 6H), 1.82 (m, 1H), 2.15-2.60 (m, 3H), 2.63 (s, 3H), 4.13 (s, 2H), 4.36 (m, 1H), 4.86 (d, 15 Hz, 1H), 4.85 (s, 2H), 5.32 (d, 15 Hz, 1H), 7.08-7.43 (m, 17H). FAB-MS: calculated for C38H41N5O5 647; found 648(M+H, 80%).
