Versuchsvorschrift

Oxalyl chloride (2.2 mL) was added to a mixture of 4-(chlorosulfonyl)benzoic acid (0.662 g, 3.0 mmol) in anhydrous dichloromethane (25 mL) followed by one small drop of N,N-dimethylformamide. The mixture was stirred at room temperature overnight. Then the mixture was then concentrated to provide 4-(chlorosulfonyl)benzoyl chloride which was used without additional purification.
