When 3-methyl-4-nitropyridine <I>N</I>-oxide was used as the starting material, a cyano group was introduced not into the 6-position, but into the 2-position. This preference may be explained by proposing a hyperconjugation effect of the 3-methyl group. The resulting nitriles were quantitatively hydrolyzed to the corresponding 4-nitropicolinic acids. These reactions provided a new route for the preparation of nitropyridinecarboxylic acids from pyridine homologues. Further, some nucleophilic substitution reactions of the products were carried out."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282679112451842","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021779141"}],"foaf:name":[{"@language":"en","@value":"Matsumura Eizo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Osaka Kyoiku University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679112451841","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021779151"}],"foaf:name":[{"@language":"en","@value":"Ohfuji Takahiko"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Osaka Kyoiku University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679112451840","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021779146"}],"foaf:name":[{"@language":"en","@value":"Ariga Masahiro"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Chemistry, Osaka Kyoiku University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00092673"},{"@type":"LISSN","@value":"00092673"},{"@type":"EISSN","@value":"13480634"}],"prism:publicationName":[{"@language":"en","@value":"Bulletin of the Chemical Society of Japan"},{"@language":"en","@value":"Bull.
