An object is to provide a process for producing a 2-haloimidazole compound represented by the formula (II), which uses inexpensive raw materials and can produce it by simple and convenient operations at low costs.
A 2,4-dihaloimidazole compound represented by the formula (I), an iodine compound, and one or two or more compounds selected from a ketone compound, an ester compound, and a nitrile compound are reacted:
wherein R represents a hydrogen atom, an alkyl group, an aryl group, a nitro group, a cyano group, a hydroxyalkyl group, a formyl group, or a carboxyl group and X is a halogen atom.
目的是提供一种生产式(II)代表的2-卤咪唑化合物的工艺,该工艺使用廉价原料,操作简单方便,生产成本低廉。
由式(I)表示的 2,4-二卤咪唑化合物、碘化合物和一种或两种或两种以上选自酮化合物、酯化合物和腈化合物的化合物进行反应:
其中 R 代表氢原子、烷基、芳基、硝基、氰基、羟烷基、甲酰基或羧基,X 代表卤素原子。
