Procedure

Combine 6-methyl-2-phenyl-benzothiazole (0.2 g, 0.98 mmol), NBS (0.2 g, 1.02 mmol), AIBN (20 mg, 0.10 mmol), carbon tetrachloride (5 mL) and reflux for 3 h. Cool the reaction mixture to ambient temperature, dilute with chloroform and wash with water. Dry the organic extracts over anhydrous Na2SO4, concentrate and purify by chromatography on silica gel eluting with hexane/EtOAc (1:0, 9:1, 8:2 and 7:3) to obtain the title compound as a white solid (0.2 g, 69%).
