Procedure

To a stirred solution of (2R,3S)-3-amino-2-phenyl-5-prop-2-yn-1-yl-2,3-dihydro-1,5-benzoxazepin-4(5H)-one (67c) (65 mg, 0.222 mmol) in dichloromethane (3 mL) was added N-[(3,5-difluorophenyl)acetyl]-L-alanine (1e) (65 mg, 0.267 mmol), HOBt (40 mg, 0.296 mmol), NMM (31 mg, 0.306 mmol) and EDAC-HCl (55 mg, 0.286 mmol). After stirring at ambient temperature under nitrogen overnight the solvent was evaporated and the residue partitioned between ethyl acetate and saturated aqueous sodium bicarbonate. The organic solution was separated, washed with 1N aqueous HCl then dried, filtered and evaporated. The residue was purified by recrystallization from 1:1 (v/v) ethyl acetate:hexanes to afford the title compound (86 mg, 74%) as a white solid. TLC Rf=0.25 (diethyl ether). 1H NMR (300 MHz, CDCl3) δ1.22 (d, 3H, J=7.0 Hz), 2.31 (m, 1H), 3.48 (s, 2H), 4.23 (m, 1H), 4.69 (d, 2H, J=2.2 Hz), 5.11 (t, 1H, J=7.0 Hz), 5.69 (d, 1H, J=7.4 Hz), 5.87 (d, 1H), 6.18 (d, 1H), 6.69-6.86 (m, 3H), 7.26-7.53 (m, 9H). MS APCI, m/z=518 (M+1). LC/MS: 2.63 min.
