Reaction Steps
Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (10 g) and butyl -4-aminobenzoate (10.8 g) are added to ethanol (100 ml), and the mixture is refluxed with stirring for 48 hours. After cooling, the precipitate is collected by filtration and recrystallized from a mixture of DMF and water to give ethyl 1,6-dihydro-2-(4-butoxycarbonylanilino)-6-oxo-5-pyrimidinecarboxylate (7.0 g). M.p. 281°-283° C.
