Versuchsvorschrift

5.9 g (28 mmol) of 2-(ethoxycarbonyloxy)benzoic acid are dissolved in 30 ml of toluene with a few drops of pyridine. 2.15 ml (29 mmol) of thionyl chloride are added dropwise and the mixture is stirred at ambient temperature for 18 h and then concentrated to dryness. The residue is precipitated from pentane. The solid is filtered off and then dried. 5.2 g of 2-(ethoxycarbonyloxy)benzoyl chloride are obtained in the form of a white solid with a yield of 80%.
