Reaction Steps

A mixture of 50 g of methyl 2-acetyl-3-(2-thienyl)acrylate, 20 g of 3-amino-1,2,4-triazole and 300 ml of ethanol is heated under reflux for 4 hours. The precipitated white crystals are collected by filtration to give 29.5 g of 6-methoxycarbonyl-5-methyl-7-(2-thienyl)-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidine, melting at 239°-240° C.
