Transformations of 2-Aminopyrimidines and Their N-Oxides under Diazotation Conditions

Sedova, V. F.,Mustafina, T. Yu.,Krivopalov, V. P.,Mamaev, V. P.

, p. 91 - 94 (2007/10/02)

The diazotation 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.
