Reaction Conditions

Reaction Steps

A mixture of tert-butyl(4-fluoro-3-methylphenoxy)dimethylsilane (step 1, 30 g, 0.12 mol), N-bromosuccinimide (24 g, 0.13 mol) and benzoylperoxide (1.5 g, 6.2 mmol) in carbon tetrachloride (75 mL) was reflux under nitrogen atmosphere for 4 h. The reaction mixture was cooled at 0° C., and the white precipitate was filtered. The filtrate washed with sodium bicarbonate aqueous solution, dried over magnesium sulfate, and evaporated. The residue was purified by column chromatography on silica gel eluting with hexane to afford 25 g (65%) of the title compound as a colorless oil:
