Abstract
It is an object of the present invention to provide a novel and advantageous process for commercially preparing of 2-cyanoimidazole compounds. More particularly, it relates to an efficient method of preparation of cyazofamid synthetic precursor by simultaneous conversion of aldoxime group to the corresponding cyano-derivative and reducing of N-oxygenated-imidazole ring to imidazole under mild conditions using reducing agent selected from the group consisting of metal salts of sulfur-containing derivatives in the presence of a polar organic solvent.
