Procedure

Aniline(1.24 mL, 13.62 mmol) was added slowly to a mixture of 4-bromo-2-methoxy-1-benzenecarbonyl chloride (3.24 g, 12.98 mmol) and triethyl amine (2.7 mL, 19.48 mmol) in dichloromethane (130 mL). After 3 hours, solvent was removed under reduced pressure. Ethyl acetate was added and the mixture was filtered. The filtrate was concentrated under reduced pressure and the residue was re-crystallized from ethyl acetate/heptane to give N1-phenyl-4-bromo-2-methoxybenzamide (2.92 g, 74%). 1H NMR (DMSO-d6) δ 3.92 (s, 3H), 7.09 (s, 1H), 7.27 (m, 1H), 7.33 (m, 2H), 7.39 (s, 1H), 7.55 (d, J=8.15 Hz, 1H), 7.71 (m, 2H), 10.10 (s, 1H).
