Procedure

0.3 g of anhydrous aluminium chloride was of 2,6-dimethylphenyl chloroformate and the mixture was heated to 200° C. at normal pressure. A further 150 g of 2,6-dimethylphenyl chloroformate and a further one gram of anhydrous aluminium chloride were then metered in over a period of 2 hours and the 2,6-dimethylchlorobenzene formed was simultaneously distilled off. The reaction did not proceed to completion and a mixture of 2,6-dimethylphenyl chloroformate and 2,6-dimethylchlorobenzene was obtained. Separation by distillation gave a 74% yield of 2,6-dimethylchlorobenzene (based on the conversion).
