Conditions

Temperature
140 °C

Procedure

200 ml of anhydrous hydrogen fluoride were placed at 0° C. in a stainless steel laboratory autoclave and 100 g of 2,6-dimethylphenyl fluoroformate were added dropwise. The autoclave was sealed and heated at a maximum temperature of 140° C. for 1.5 hours. The reaction mixture was worked up as described in Example 9. 2,6-Dimethylfluorobenzene was obtained in a yield of 75%.
