Procedure
A 500 ml flask was charged with 3-bromophenol (A) (25 g, 144 mmol), THF (200 ml) and triethylamine (14.67 g, 145 mmol). The flask was cooled to 0° C. in an ice bath, and chlorotriethylsilane (21.8 g, 144 mmol) was added dropwise. The mixture was allowed to stir at room temperature to completion over 2 h. The hydrochloride salt was then filtered. Removal of solvents followed by flash chromatography afforded 3-bromo-O-triethylsilylphenol (J) as a clear liquid (30.4 g, 73%).
