Reaktionsschritte
Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (21.5 g) and 2-butoxyaniline (24 g) are added to pyridine (50 ml), and the mixture is refluxed with stirring for 18 hours. The reaction mixture is concentrated to dryness. The residue is recrystallized from DMF to give ethyl 1,6-dihydro-2-(2-butoxyanilino)-6-oxo-5-pyrimidinecarboxylate (20 g). M.p. 209°-211° C.
