Benzimidazole is also synthesized from o-phenylenediamine and mono or di-basic acid. In this method, the diamine is simply heated with excess acid (Fischer, 1905).This procedure has been recommended as a means of identifying fatty acid α-hydroxy acid as well as phenylacetic acid and diphenylacetic acid are converted into the corresponding benzimidazoles when heated with o-phenylenediamine.
