Procedure

The objective compound was prepared by the same procedure for the intermediate 1, using a 2-(4-benzyloxy-3-bromo-phenyl)-propionic acid (1.0 g, 3.00 mmol), SOCl2 (1.10 mL, 14.9 mmol), and 2-amino-4,6-dichloro-benzoic acid methyl ester (0.50 g, 2.40 mmol). After normal workup, the pure objective compound (0.91 g, 71%) was obtained as white solid by a flash column chromatography (n-hexane:EtOAc=5:1): 1H NMR (200 MHz, CDCl3) δ 1.53 (s, 3H, CH3), 3.62 (q, J=7.1 Hz, 1H, CH), 3.79 (s, 3H, CO2CH3), 5.16 (s, 2H, CH2Ph), 6.94 (d, J=8.4 Hz, 1H, ArH), 7.15 (d, J=2.30 Hz, 1H, ArH), 7.20 (dd, J=8.6, 2.0 Hz, 1H, ArH), 7.31-7.48 (m, 5H, ArH), 7.54 (d, J=2.4 Hz, 1H, ArH), 8.41 (d, J=2.0 Hz, 1H, ArH), 9.15 (br s, 1H, NH).
