interaction of 3-amino-3-thioxopropanamides with 2-anilinomethylene derivatives of dimedone, 1,3-cyclohexanedione and Meldrum’s acid led to the formation of 2-(2-amino-2-oxoethyl)-6-thioxo-1,6-dihydropyrimidine-5-carboxamides. The latter were alkylated in alkaline medium with the formation of 4-(alkylthio)pyrimidine-5-carboxamide derivatives.
