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.
提供一种在工业规模下,可以在低成本且高纯度下生产2,3′-联吡啶-6′-酮的生产工艺,而无需使用昂贵的催化剂或特殊设备。生产2,3′-联吡啶-6′-酮的工艺包括将乙酰吡啶衍生物与式(II)至(V)所代表的化合物中的至少一种进行反应,合成联吡啶衍生物,然后通过一锅法水解联吡啶衍生物。在式(II)至(V)中,R2至R8、X和Y分别代表给定的基团。
