Procedure

3-Bromo-2-methylbenzoic acid (2000 mg) was added to dichloromethane (50 mL) and N,N-dimethylformamide (1 mL). Oxalyl chloride (649 mg) was added and the solution was stirred for three minutes. The mixture was washed with 1 M aqueous HCl three times, washed with brine, and dried on anhydrous sodium sulfate. After filtration, the solvent was removed under vacuum to yield the product.
