Versuchsvorschrift

78 g of thionyl chloride were added to 50 g of 3,4-dimethylbenzoic acid and the reaction mixture was heated at reflux for 3 hours. The reaction mixture was subsequently concentrated, and the residue was taken up twice in toluene and concentrated again. 53 g of 3,4-dimethylbenzoyl chloride were obtained.
