Reaction Steps
Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (20 g) and 2-fluoroaniline (15.6 g) are added to ethanol (200 ml), and the mixture is refluxed with stirring for 24 hours. After cooling, the precipitate is collected by filtration and recrystallized from DMF to give ethyl 1,6-dihydro-2-(2-fluoroanilino)-6-oxo-5-pyrimidinecarboxylate (4.5 g). M.p. 250°-252° C.
