Procedure

A plastic bottle having a 25 ml. capacity was charged with 2.42 grams (0.01 mole) of 2-bromo-1,3-dimethyl-5-t-butylbenzene, 4.12 grams (0.04 mole) of metaxylene and 4.0 grams of liquid HF. The contents were stirred at 0° C. for 2.5 hours. Analysis of the crude product showed about 10% conversion of 2-bromo-1,3-dimethyl-5-t-butylbenzene to give equal molar amounts of 1,3-dimethyl-5-t-butylbenzene and 2-bromo-1,3-dimethylbenzene.
