반응 단계
3.8 g of 1-formyl-1-methylhydrazine are added dropwise to a solution of 16 g of ethyl 2-(2,3,4,5-tetrafluorobenzoyl)-3-ethoxy-acrylate in 60 ml of ethanol, while cooling with ice and stirring. The mixture is stirred at room temperature for 1 hour, 60 ml of water are added, the mixture is cooled with ice and the precipitate is filtered off with suction and washed with water/ethanol (1:1). 12 g of ethyl 2-(2,3,4,5-tetrafluorobenzoyl)-3-(2-formyl-2-methylhydrazino)-acrylate of melting point 92° C. are obtained.
