反应详情

To 2.5 mL benzyl alcohol in 80 mL THF is added 1.87 g NaH. After one hour stirring at room temperature, 5.0 g of 2,4-Difluorobenzonitrile is added. After stirring one hour, the reaction is quenched with excess water and concentrated in vacuo. The residue is redissolved in ethyl acetate and washed with water, brine, dried over sodium sulfate, filtered and concentrated in vacuo. The product is recrystallizde in carbon tetrachloride to give 3.24 g (39.7%) of the title compound.
