摘要

A manufacturing method of an imidazole compound represented by a formula (1) below includes reacting 1-arylimidazole with a halogen-atom substituted compound. For performing this reaction, in a reaction system, a mole number N_f(2) [mol] of the halogen-atom substituted compound and a total volume V_sol [liter] of an ether solvent having at most 5 carbon atoms satisfy a relationship of V_sol/N_f(2)≤3.;In the formula (1): R₁ and R₄ represent a substituent and the like; Z₁ represents a group of atoms necessary for forming a hydrocarbon cyclic group and the like; R₂ and R₃ represent a bond, a hydrogen atom or an aromatic hydrocarbon group; Z₂ represents a group of atoms necessary for forming a five-membered hydrocarbon ring and the like together with C-C; and m represents an integer of 1 to 5.
