To a stirred solution of 2-acetoxy-4-fluorobenzoic acid (852 mg, 4.9 mmol) in dry dichloromethane (40 mL) under dry nitrogen were added sequentially dry DMF (8 drops), dry pyridine (0.5 mL) and oxalyl chloride (0.5 mL). After stirring 1.5 h at room temperature, the reaction mixture was evaporated to dryness to afford 2-acetoxy-4-fluoro-benzoyl chloride.
