Reaction Steps
112.5 g. of 3-Methyl-5-aminoisoxazole (1.14 mol.) and 248 g. of ethoxymethylenemalonic acid diethyl ester (1.14 mol.) are heated with stirring for 45 minutes at 130°. After this period, ethanol is removed under reduced pressure. The residue solidifies on cooling and is recrystallized from ethanol, m.p. 134°-136°, yield 245 g. (80%).
