PROCEDURE

实验过程

Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (15 g) and 2-(1-methylethoxy)aniline (11.5 g) are added to ethanol (100 ml), and the mixture is refluxed with stirring for 17 hours. After cooling, the precipitate is collected by filtration and recrystallized from DMF to give ethyl 1,6-dihydro-2-[2-(1-methylethoxy)anilino]-6-oxo-5-pyrimidinecarboxylate (8.5 g). M.p. 205°-207° C.
