Procedure

To a solution of 2-bromomethyl-6-(cyclopropanecarbonyl-amino)-3-fluoro benzoic acid methyl ester (1 g, 3 mmol) and Et3N (1.25 ml, 9 mmol) in DMF (10 ml) was added (1S)-1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethylamine (870 mg, 3.2 mmol). The mixture was heated at 90° C. for 20 hrs. The reaction mixture was cooled to room temperature and extracted with water (50 ml) and EtOAc (50 ml). The organic layer washed with water (50 ml), brine (25 ml), dried over Na2SO4 and concentrated. The resulted oil was purified by chromatography to give (1S)-cyclopropanecarboxylic acid {2-[1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-7-fluoro-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide as a white solid (800 mg, 55% yield): mp, 176-178° C.; 1H NMR (CDCl3) δ 0.88-0.92 (m, 2H, c-propylCH2), 1.09-1.12 (m, 2H, c-propylCH2), 1.47 (t, J=7.0 Hz, 3H, OCH2CH3), 1.64-1.68 (m, 1H, c-propylCH), 2.98 (s, 3H, CH3), 3.63-3.73 (m, 1H, CHHSO2), 3.87 (s, 3H, CH3), 4.05-4.28 (m, 4H, CHHSO2+CNHH+OCH2CH3), 4.49 (d, J=18 Hz, 1H, C), 6.85-6.92 (m, 1H, NCH), 6.86-6.93 (m, 3H, Ar), 7.04 (t, J=8 Hz, 1H, Ar), 8.45-8.55 (m, 1H, Ar), 10.32 (s, 1H, NHCO); 13C NMR (CDCl3) δ 8.26, 8.27, 14.67, 16.04, 41.50, 44.67, 51.30, 55.39, 55.96, 64.65, 111.63, 112.21, 118.95, 119.26, 119.68, 119.92, 126.43, 126.74, 128.99, 134.48, 134.53, 148.98, 149.88, 150.31, 154.22, 168.89, 172.39. Anal Calcd for C24H27FN2O6S: C, 58.76; H, 5.55; N, 5.71. Found: C, 58.60; H, 5.33; N, 5.65.
