Abstract

An improved procedure for the preparation of aromatic heterocyclic N-oxides is described. Nitrogen containing heterocyclic compounds gave their N-oxides in excellent yields by the reaction of m-CPBA in DMF/MeOH in the presence of HF in a short time under mild reaction conditions. The presence of HF and MeOH is crucial for the reaction.
