Jovanovic, Misa V. published the artcileSyntheses of some pyrimidine N-oxides, Synthetic Route of 31401-45-3, the publication is Canadian Journal of Chemistry (1984), 62(6), 1176-80, database is CAplus.
Various monosubstituted pyrimidines and methylpyrimidines were N-oxidized with a number of different peracids. In general, they are more susceptible to side reactions accompanying N-oxidation than other π-deficient diazines and triazines. Unsym. pyrimidines, which can potentially yield 2 isomeric products, were N-oxidized preferentially at the site para to strong electron-donating substituents. Weaker ring-activating groups, such as Me, are mainly ortho-directing and only aid in the N-oxidation of pyrimidine nuclei having ortho/para-directing substituents.
