Procedure
To a solution of 2-methyl-6-phenoxy-benzothiazole (0.06 g, 0.24 mmol) in 5 ml of CCl4 was added NBS (0.039 g, 0.22 mmol) and AIBN (0.004 g, 0.024 mmol). The reaction mixture was heated at 100° C. for 2 h under nitrogen atmosphere. After the completion of the reaction mixture (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure and the residue was purified by column chromatography on silica (230-400M) using 1% ethyl acetate/hexane eluent to give the desired product (0.005 g, 6.3%).
