Abstract
A production process where 2,3′-bipyridyl-6′-one can be produced in high purity at low cost on an industrial scale without using an expensive catalyst or special equipment is provided. A process for producing 2,3′-bipyridyl-6′-one comprises reacting an acetylpyridine derivative with at least one of compounds represented by formulae (II) to (V) to synthesize a bipyridine derivative and hydrolyzing the bipyridine derivative by one-pot preparation. In formulae (II) to (V), each of R2 to R8, X and Y represents a given group.
