Reaction Steps

Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (8 g) and 2-ethoxyaniline (6.1 g) are added to ethanol (60 ml), and the mixture is refluxed with stirring for 48 hours. After cooling, the precipitate is collected by filtration, washed with ethanol and recrystallized from a mixture of DMF and water to give ethyl 1,6-dihydro-2-(2-ethoxyanilino)-6-oxo-5-pyrimidinecarboxylate (7.5 g). M.p. 220°-221° C.
