Abstract
Treatment of 2-R-4,6-dichloropyrimidines with hydroxylamine gives 2-R-4-chloro-6-hydroxyaminopyrimidines, which are converted to mono- and diacyl derivatives upon acylation. Oxidation of 4-chloro-6-hydroxyaminopyrimidines with manganese dioxide or ozone gives the first reported synthesis of 4-chlorine-containing 6-nitroso- or 6-nitropyrimidines, respectively.
