PROCEDURE
实验过程
163 g of 1-(2-furyl)methyl-5-aminopyrazole (1mol) and 216 g of ethoxymethylene malonic acid diethyl ester (1 mol) are heated to 130° (bath temperature) until the theoretical amount of alcohol is distilled off. The remaining oil, [[[1-(2-furyl)methyl-5-pyrazolyl]aino]methylene]malonic acid diethyl ester, is recrystallized from methanol, yield 280 g (84%), m.p. 84°-86°.
