Versuchsvorschrift

2-bromo-6-chlorotoluene (20.55 g) and N-bromosuccinimide (19.6 g) were stirred together in carbon tetrachloride (100 ml) under reflux for 22 hours exposure to radiation from an infrared lamp. The resulting solution was cooled in ice, filtered and evaporated to yield the title product which was dissolved in petroleum ether (60-80). Part was recrystallised therefrom as pink needles (8.5 g) and part was recovered by evaporation as a dark orange solid (17.7 g) (total yield 26.2 g. 92%).
