実験手順
To a solution of 2-fluoro-4-bromobenzonitrile (2.0 g, 10 mmol) in 10 mL of THF, cooled to −15° C., was added a solution of potassium t-butoxide (10 mL, 10 mmol) over 7 min. The cooling bath was removed, and the reaction stirred for another 40 min. The reaction was poured into ether/10% HCl, and the ether layer was separated. The ether layer was washed with water and saturated brine, dried over sodium sulfate, and concentrated to give 2.5 g of 2-t-butoxy-4-bromobenzonitrile.
