Participants

Reaction Steps

A solution of methyl 3-[(1,1-dimethylethyl)dimethylsilyl]oxy-4-methylbenzoate (11.36 g, 40.5 mmol) from Preparation 13, N-bromosuccinimide (6.5 g, 36.5 mmol), and AIBN 100 mg, 0.61 mmol) in CCl4. The reaction mixture is stirred at room temperature for 1 hour while exposed to a high intensity light bulb. The precipitate is removed by suction filtration and the filtrate is concentrated. The residue is purified by silica gel chromatography (1% tetrahydrofuran/petroleum ether). An oil of methyl 4-(bromomethyl)-3-[[(1,1-dimethylethyl)-dimethylsilyl]oxy]benzoate is obtained 99.87 g, 75%).
