<p>A process by which a 5-(2'-pyridyl)-2-pridone derivative can be industrially advantageously produced. The process, which is for producing a 5-(2'-pyridyl)-2-pyridone derivative represented by the general formula (VI), is characterized by reacting a pyridine derivative represented by the general formula (I) with a brominating agent to obtain a 5-bromopyridine derivative represented by the general formula (II), reacting the 5-bromopyridine derivative with a metallizing agent to obtain an organometallic compound represented by the general formula (III), reacting the organometallic compound with a 2-sulfonypyridine derivative represented by the general formula (IV) to obtain a 6-alkoxy-3,2'-bipyridine derivative represented by the general formula (V), and hydrolyzing the 6-alkoxy-3,2'-bipyridine derivative. (I) (II) (III) (IV) (V) (VI) (In the formulae, the symbols are the same as defined in the description.).</p> |
