Dimethylformamide → 2-Chloro-5-(trifluoromethyl)benzoyl chloride

Participants

Reaction Steps

2-Chloro-5-(trifluoromethyl)benzoic acid (224 mg, 1.0 mmol) in dichloromethane (1.5 mL) was treated with a solution of oxalyl chloride (1.5 mL of 2 M in dichloromethane, 3 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred overnight at ambient temperature. The excess oxalyl chloride was removed in vacuo to afford 2-chloro-5-(trifluoromethyl)benzoyl chloride.
