Procedure

3-Fluoro-5-cyanobenzoic acid (1.0 g, 6 mmol) was treated with a solution of oxalyl chloride (12 mL of 2.5 M in dichloromethane, 30 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred at ambient temperature for 2.5 hours. The excess oxalyl chloride was removed in vacuo to afford 3-fluoro-5-cyanbenzoyl chloride.
