2-Sulfonylpyridine derivatives can be industrially produced efficiently by reacting a sulfonyl cyanide derivative with an α,β-unsaturated carbonyl compound and a 2-{[(2-pyridyl)methyl]thio}-1H-benzimidazole skeleton can be formed in one step in a good yield by reacting this type of the 2-sulfonylpyridine derivative with a 2-methylthio-1H-benzimidazole derivative in the presence of an organolithium compound.

PCT No. PCT/JP97/03144 Sec. 371 Date May 6, 1998 Sec. 102(e) Date May 6, 1998 PCT Filed Sep. 8, 1997 PCT Pub. No. WO98/11071 PCT Pub. Date Mar. 19, 1998A process for preparing halogenopyridine derivatives represented by the general formula (II) wherein X and Y each independently represent a halogen atom, comprises reacting a halogeno-2-sulfonylpyridine derivative represented by the general formula (I) wherein X is as defined above and R1 represents an alkyl group etc., with a halogenating agent. The halogenopyridine derivatives can be produced with high purity and in a simple and easy and industrially advantageous manner.
