Procedure

To a 50 ml round bottom flask is added 4-(4-methylphenyl)butyl tert-butyldimethylsilyl ether (0.25 g, 0.89 mmol), N-bromosuccinimide (0.158 g, 0.89 mmol), benzoyl peroxide (2.17 mg, 0.0089 mmol) and 10 ml carbon tetrachloride. This mixture is refluxed overnight after which it is cooled and filtered. The filtrate is concentrated and the resulting crude residue is purified by flash chromatography in ethyl acetate-hexanes to afford the product.
