Procedure

To a stirred solution of (2S)-2-amino-2-(4-fluorophenyl)-N-[(2R,3S)-4-oxo-2-phenyl-2,3,4,5-tetrahydro-1,5-benzoxazepin-3-yl]acetamide (65b) (81 mg, 0.199 mmol) in dichloromethane (2mL) under nitrogen was added 3,5-difluorophenylacetic acid (40 mg, 0.232 mmol), HOBt (35 mg, 0.259 mmol), NMM (30 mg, 0.297 mmol) and EDAC-HCl (50 mg, 0.261 mmol). The mixture was stirred 5 h at ambient temperature then evaporated. The residue was dissolved in ethyl acetate and extracted in succession with saturated sodium bicarbonate, 1N aqueous HCl, and brine. The organic solution was dried, filtered and evaporated. The residue was purified by flash chromatography on silica gel eluting with 6:1 (v/v) dichloromethane:ethyl acetate (TLC Rf=0.42) to afford the title compound (85 mg, 76%) as a white solid. 1H NMR (300 MHz, CDCl3) δ3.54 (s, 2H), 5.08 (t, 1H, J=7.0 Hz), 5.19 (d, 1H, J=6.5 Hz), 5.79 (d, 1H, J=7.0 Hz), 6.16 (br d, 1H, J=6.5 Hz), 6.62 (br d, 1H, J=7.0 Hz), 6.66-6.86 (m, 3H), 6.87-7.04 (m, 3H), 7.08-7.39 (m, 10H), 7.50 (br s, 1H). MS APCI, m/z=560 (M+1). LC/MS: 2.61 min.
