0.1 mL of methylhydrazine and 10 mL of anhydrous ethanol were added to a 250 mL three-necked flask, stirred and heated to 50°C. Subsequently, 0.1 mol of ethyl trifluoroacetoacetate was slowly added dropwise. After the dropwise addition was completed, the reaction mixture was heated to reflux for 5 hours. Upon completion of the reaction, the mixture was cooled to promote crystallization. The resulting yellow solid was collected by vacuum filtration and dried. The yield of the final product was 85.8%. | [References]
