Procedure

To 1-methyl-3-tert-butyl-benzene (551 mg, 3.72 mmol), NBS (730 mg, 1.1 eq) and AIBN (14 mg, catalytic amount) was added CCl4 (8 mL), which was then refluxed for 2 h. The suspended particles were removed by filtration, and washed with CCl4. The organic layers were combined and concentrated under reduced pressure to give 860 mg of a yellow liquid (which was identified by NMR to contain about 15% dibromo derivative).
