実験手順

0.5 g of anhydrous aluminium chloride was added to 15 g of 2,4-dimethylphenyl chloroformate and the mixture was heated at 200° C. for 3 hours at normal pressure. The reaction mixture was cooled and worked up as described in Example 1. 2,4-Dimethylchlorobenzene was obtained in a yield of 20%, which is considerable despite the unfavourable substitution pattern.
