Reaction Steps

3-Fluoro-5-cyanobenzoic acid (2.5 g, 15.14 mmol) was treated with a solution of oxalyl chloride (30 mL of 2.5 M in dichloromethane, 75 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-cyanobenzoyl chloride.
