Procedure
To a solution of 1-bromo-2-methyl-3-nitrobenzene (50.0 g, 0.231 mol) in CCl4(500 mL) was added NBS (41.2 g, 0.231 mol) and BPO (6.51 g, 0.0231 mol), and the mixture was stirred at reflux for 1 h. Then the mixture was washed with 1 N HCl (300 mL*3), dried over Na2SO4, concentrated in vacuo. The residue was purified via chromatography (petrol ether) to give 1-bromo-2-(bromomethyl)-3-nitrobenzene.
