반응 단계

640.5 g (4.6 mol) of difluorobenzonitrile were dissolved in 3.5 l of methanol and then cooled to 0-5° C. 828.8 g of 30% strength sodium methoxide solution were added dropwise in this temperature range, and the reaction mixture was stirred at room temperature overnight. Then the reaction mixture was added to 20 l of water and the precipitate was filtered off with suction and washed twice with water and twice with heptane. The solid was dried in vacuo at 50° C. Yield: 740 g (99% of theory) of a white solid with a purity of >95% according to GC.
