Procedure

4-Bromo-2-chlorotoluene (7.02 g) and N-bromosuccinimide (6.07 g) was stirred in chlorobenzene (50 ml) under ultraviolet light at 100° C. for 18 h. The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by medium-pressure liquid chromatography, eluting with iso-hexane, to give a colourless oil (2.65 g).
