4-fluoropyrimidine 1-oxides, obtained via three-component heterocyclization, was studied under various reduction conditions. An effective preparative method for the synthesis of 4-fluoropyrimidines from readily available starting materials was elaborated. 4-Fluoro-substituted tetrahydroquinazolines and tetrahydroquinazoline N-oxides were demonstrated to be highly reactive in aromatic nucleophilic substitution.
