Synthesis of substituted 2- and 4-hydroxyaminopyrimidines
The reaction of 2- and 4-chlorine-containing alkyl(aryl)pyrimidines with hydroxylamine was studied. It was shown that, depending on the amount of hydroxylamine, N,O-dipyrimidinylhydroxyamines or the corresponding 2- and 4-hydroxyaminopyrimidines are formed together with 2- and 4-oxodihydropyrimidines.
