Reaction Steps
To a solution of 2-bromo-4-fluoro-benzonitrile (2000 mg, 9.9995 mmol) in DMF (20 mL), potassium trimethylsilanolate (2565.7 mg, 19.999 mmol) was added portionwise and the reaction mixture stirred at room temperature for 1 h. The mixture was diluted with ethyl acetate (100 ml), washed with an aqueous saturated solution of ammonium chloride (100 ml) and brine (3×100 ml), dried over sodium sulphate and concentrated under vacuum to give the title compound (2000 mg) which was used in the next step without purification.
