Procedure

Oxalyl dichloride (6.1 g, 48 mmol) was added to a solution of 4-bromo-3-fluoro-benzoic acid (7 g, 32 mmol) in DCM (80 mL) at 0° C. followed by DMF (0.2 mL) and the reaction mixture was stirred at RT for 2 h and then conentrated under vacuum to provide crude 4-bromo-3-fluoro-benzoyl chloride.
