A molar equivalent of pyridine N-oxide was added to 6-methyl-4(3H)-pyrimidinone (I) and 4(3H)-quinazolinone (V), and heated with addition of platinum-added palladium carbon, catalyst(Pd/Pt-C) by which products were compounds (III, IV, VI, and VII) formed by reaction at respective 2-position. III, IV, and VII are new compounds hitherto unreported in literature. These were derived to IIIa, IVb, and VIIb to determine their structure. The same reaction of I and V with 0.5 mole of pyridine results in the formation of III and VI in approximately double the yield of the former. It seems possible to synthesize various nonsymmetric compounds by the use of a different N-oxide.
