<p>[Problem] The present invention addresses the problem of providing a production method for synthesizing a nitrogenated heterocyclic N- oxide compound with high efficiency and in a safe manner. The present invention also addresses the problem of providing a novel N- oxide compound. [Solution] Provided is a method for producing a nitrogenated heterocyclic N -oxide compound represented by formula (2), e.g., 2, 2 ,7 ,9 -tetramethyl- 2H- pyrano[2,ʌ- g]quinoline N -oxide, by oxidizing a nitrogenated heterocyclic compound represented by formula (1), e.g., 2, 2 ,7, 9 -tetramethyl- 2H- pyrano[2, 3- g]quinolone , with a persulfate salt.</p> |
