PREPARATION OF HIGH PURITY THIABENDAZOLE

摘要

Process for preparing 2-(4'-thiazolyl)-benzimidazole (generic name: thiabendazole) by the acid-catalyzed condensation of ophenylenediamine and 4-cyanothiazole using as a solvent polar organic compounds in which the reactants, catalysts and impurities are soluble, and the product, thiabendazole, is substantially insoluble.
