Procedure
To a stirred solution of 3-bromophenol (0.60 g, 3.47 mmol) in dry THF (15 mL) under nitrogen was added Et3N (0.48 mL, 3.47 mmol). A clear yellow solution formed immediately; after cooling to 0° C., dimethylethylsilyl chloride (0.43 g, 0.49 mL, 3.47 mmol) was added by syringe over a period of 10 minutes. The yellow color disappeared in 10 min, and a white cloudy solution formed. After 3 hr the thick reaction mixture was filtered, washed with 15 mL of hexane, and filtered again. Concentration gave a clear oil (quantitative weight recovery) that was used in the next step without any purification.
