N-Bromosuccinimid (3.9 g, 22 mmol) was added to 4-chloro-2-methoxy-5-methylanilin (4.04 g, 20 mmol) dissolved in acetonitril (200 ml). The reaction was stirred at r.t. overnight, and the solvent was evaporated. The residue was purified by column chromatography (silica gel, methylene chloride) to yield the title compound (3.1 g, 62%) as an orange solid.
