YieldReaction ConditionsOperation in experiment
33.8 g With potassium fluoride In N,N-dimethyl-formamide at 140 - 160℃; In the solution prepared in step (3)29.0 g of KF was charged under stirring,And then incubating the mixture at a temperature of 140-160 DEG C until the content of 2,3,4-trichlorobenzonitrile reaches 2percent(5) under normal pressure to do spin-drying solvent DMF,The resulting brown-yellow granular solid was recrystallized by dissolving 200 mL of toluene,Cooling to about 0 overnight,Filtration,And dried to give 33.8 g of 3-chloro-2,4-difluorobenzonitrile as a pale yellow granular solid in an amount of 98.637percent (GC) in a molar yield of 65.0percent Benzene);
