Participants

Reaction Steps

To a solution of 100 mg (0.142 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, trifluoroacetate (Example 36, Step A) in 2 mL of dry methylene chloride under nitrogen atmosphere was added 0.040 mL (0.28 mmol) of triethylamine followed by 0.021 mL (0.16 mmol) of 2-methoxyphenyl isocyanate. The reaction mixture was stirred at room temperature for 30 minutes, diluted with 100 mL of ethyl acetate, washed with 25 mL of saturated aqueous ammonium chloride, 25 mL of saturated aqueous sodium bicarbonate and 25 mL of brine. The organic layer was dried over magnesium sulfate, filtered and the solvent removed under vacuum to afford 102 mg (97%) of the product as a white foam. 1H NMR (200 MHz, CD3OD): δ 1.38 (s, 6H), 1.80 (m, 1H), 2.15-2.50 (m, 3H), 3.80 (s, 3H), 4.19 (s, 2H), 4.27 (m, 1H), 4.68 (d, 16 Hz, 1H), 5.00 (s, 2H), 5.30 (d, 16 Hz, 1H), 6.90 (m, 3H), 7.10-7.45 (m, 17H), 7.92 (m, 1H). FAB-MS: calculated for C44H45N5O6 739; found 740 (M+H, 60%).
