Procedure

In 60 ml of anhydrous ethyl ether, was suspended 6.2 g of 4-acetyloxy-2-methylbenzoic acid. To the suspension, was added 8.0 g of phosphorus pentachloride. The suspension was stirred for 3 hours at room temperature. The reaction mixture was freed from the solvent by distillation under reduced pressure, admixed again with ethyl ether, and freed from the solvent by distillation to obtain 4-acetyloxy-2-methylbenzoyl chloride.
