442 g of 2-chloro-6-methoxytoluene are dissolved in 2420 ml of carbon tetrachloride and, together with 516 g of N-bromosuccinimide, heated at reflux for 2 h while 5.8 g of AIBN are added. The solid is filtered off and washed with a small amount of carbon tetrachloride, the filtrate is concentrated, and the residue which remains is fractionated. 483 g of colorless oil are obtained (b.p. 100° C./1.4 mbar, m.p. 44-47° C.).
