Reaction Steps

A 500-mL three-neck, round bottomed flask, equipped with a stir bar, temperature probe and nitrogen inlet, was charged with 2-bromo-6-fluorophenol (25 g, 130.9 mmol, 1.00 eq), DMF (252 mL, 0.52 M), imidazole (12.3 g, 181 mmol, 1.38 eq) and tertbutyldimethylsilyl chloride (19.7 g, 131 mmol, 1.00 eq). The mixture was heated at 60° Celsius for 3 hours. The reaction was cooled to room temperature and diluted with water. The aqueous phase was extracted with ethyl acetate and the resultant organic solution washed with water and brine and dried over sodium sulfate. The organic phase was concentrated to dryness and purified using FCC to provide (2-bromo-6-fluorophenoxy)(tert-butyl)dimethylsilane as a colorless oil (33 g, 82%).
