The diazotization of 2-aminopyrimidines and their N-oxides in solutions with various acidities was studied. It is shown that the amino group in pyrimidine N-oxides is not diazotized in strongly acidic media and that bromination in the 5 position of the pyrimidine ring is observed in concentrated hydrobromic acid. When the reaction was carried out in moderately acidic media, it was possible to synthesize the difficult-to-obtain 2-halopyrimidine N-oxides. © 1983 Plenum Publishing Corporation.
