Versuchsvorschrift

To a solution of 4-fluoro-3-hydroxybenzonitrile (25.0 g, 182 mmol), diisopropylethylamine (47.7 mL, 273 mmol) in dichloromethane (530 mL) was added chloromethyl methyl ether (16.6 mL, 219 mmol) dropwise at 0° C., and the mixture was stirred at room temperature overnight. Water was added, and the mixture was extracted with dichloromethane. The organic layer was washed with brine and dried on anhydrous sodium sulfate. The solvent was removed under reduced pressure to give 4-fluoro-3-methoxymethoxybenzonitrile (33.0 g, quant.), which was used for the next step without purification.
