实验步骤: Sodium hydride (60 mg, 2.5 mmol) was slurried in DMF (15 mL) and treated with dry methanol (120 μl, 96 mg, 3.0 mmol). After stirring for 10 minutes at 25° C., the solution was cooled to −25° C. and treated with 2,3-difluoro-4-iodobenzonitrile (500 mg, 1.9 mmol). After 25 minutes, the mixture was quenched by addition of 10% citric acid solution (5 mL) and warmed to 25° C. The mixture was extracted with ethyl ether (2×15 mL), the combined ether phases washed with water (5 mL), brine, dried (sodium sulfate) and evaporated to give 3-fluoro-4-iodo-2-methoxybenzonitrile (500 mg, 1.8 mmol): LC/MS (m/z=277). the solution was cooled to −25° C. After 25 minutes the mixture was quenched by addition of 10% citric acid solution (5 mL) warmed to 25° C The mixture was extracted with ethyl ether (2×15 mL) the combined ether phases washed with water (5 mL), brine dried (sodium sulfate) evaporated
