Reaction Steps

3-Chloro-5-cyanobenzoic acid (0.82 g, 4.97 mmol) was treated with a solution of oxalyl chloride (10 mL of 2.5 M in dichloromethane, 25 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-chloro-5-cyanobenzoyl chloride.
