Reaction Steps
Oxalyl chloride (4.4 mL of 2M in chloroform, 8.8 mmol) was added to a suspension of 4-(chloromethyl)benzoic acid (1 g, 5.7 mmol) in dichloromethane. N,N-dimethylformamide (4 drops) was added to catalyze the reaction. After 1 hour analysis by HPLC indicated 100% clean conversion. The reaction mixture was concentrated under vacuum to provide 4-(chloromethyl)benzoyl chloride.
