Procedure

To a solution N-[(3,5-difluorophenyl)acetyl]-L-serine (4b) (75 mg) in dichloromethane (15 mL) at 0° C. under N2, was added racemic 2,3-cis-3-amino-2-(2,5-difluorophenyl)-2,3-dihydro-1,5-benzothiazepin-4(5H)-one-HCl (1d) (100 mg) followed by the HOBt-hydrate (97 mg) and NMM (32 μL). Reaction stirred for 5 min. and then added EDAC-HCl (84 mg) and NMM (50 μL). The reaction mixture was stirred 2H at 0° C. under N2, concentrated in vacuo and partitioned between water (100 mL) and ethyl acetate (125 mL). The organic phase was collected and consecutively washed with water, saturated aqueous sodium bicarbonate, brine, dried, filtered and evaporated to yield a mixture of the title compound and (2S)-2-{[(3,5-difluorophenyl)acetyl]amino}-N-[(2S,3S)-2-(2,5-difluorophenyl)-4-oxo-2,3,4,5-tetrahydro-1,5-benzothiazepin-3-yl]-3-hydroxypropanamide. The crude product (165 mg) was purified by flash chromatography (80% ethyl acetate/hexanes) to afford the title compound (60 mg, 73%) as a white solid. 1H NMR (300 MHz, d6-DMSO) δ(d, 3H), 3.48 (s, 2H), 4.21 (q, 1H), 4.74, (t, 1H), 4.85 (bs, 1H), 5.50 (d, 1H), 6.93 (d, 2H), 7.09 (m, 1H), 7.18-7.35 (m, 4H), 7.45-7.55 (m, 2H), 7.71 (t, 2H), 8.17 (d, 1H), 10.68 (s, 1H). MS APCI, m/z=548 (M+1). LC/MS: 2.34 min.
