Method of producing formylimidazoles
 In producing formylimidazoles by catalytically oxidizing the corresponding 4- or 5-hydroxymethylimidazoles, the catalytic oxidation is carried out in the presence of a noble metal catalyst while oxygen or air is blown into the reaction system. In this case, it is particularly desirable that the catalytic oxidation in the presence of a noble metal catalyst be carried out in a solvent comprising an aqueous alkali or in a mixed solvent composed of an aqueous alkali and an organic solvent immiscible with water.
