실험 절차
5 g of 2-amino-5-methyl-3-ethoxycarbonyl-thiophene is dissolved with 2.7 g of methyl 4-cyanobenzoate in 40 ml of dioxane. Gaseous HCl is then passed through the solution for 5 hours. After customary working up, 6 g of methyl 4-(3,4-dihydro-4-oxo-6-methyl-thieno-[2,3-d]-pyrimidin-2-yl)-benzoate are obtained.
