Reaction Steps
A mixture of methyl 4-bromo-2-methylbenzoate (45 g), N-bromosuccinimide (38.4 g) and dichloromethane was heated at reflux under irradiation from two 120 Watt tungsten lamps for five hours. The mixture was then cooled to -15° C. and filtered and the filtrate was evaporated. The residue was recrystallised from cyclohexane to give methyl 4-bromo-2-(bromomethyl)benzoate as pale yellow crystals (39.9 g), m.p. 79.2° C.
