The subjects of the present study are fluorine-con- taining pyrimidine derivatives which constitute a new class of potential biologically active substances and compounds possessing anticorrosion properties. De- spite the fact that some fluoropyrimidines have long been known [1–11] and have found wide applpication (eg, 5-fluorouracil and Ftorafur), methods of syn- thesis and chemical properties of fluorine-containing nitrogen heterocycles have been studied fairly poorly, so ...
