To a solution of 1-(3-chloro-4-methoxyphenyl)ethanone (1.0 g, 5.42 mmol) in MeOH (29.5 mL) was added a solution of bromine (0.33 mL, 6.50 mmol) in MeOH (10 mL) at RT. The reaction mixture was then stirred for 2 h, quenched with ice and extracted with DCM (2×20 mL). The combined organic layers were washed with water, dried over Na2SO4, and concentrated in vacuo to afford 2-bromo-1-(3-chloro-4-methoxyphenyl)ethanone (1.0 g, 70%) as solid.
