Abstract

In this study new imidazoles derivatives were synthesized.The first stage involved preparation of 3-(4,5-diphenyl-1Himidazole-2-yl)phenol(AA1)by reacting Benzil with Substituted benzaldehyde in presence of sodium cyanide catalyst .The second stage involved the synthesis of Synthesis of 3-(4, 5 - diphenyl-1H imidazole-2-yl) sulfonamide(AA2) using TEA in glacial acetic acid. Finally the compound were synthesized using the three component system (Compound AA2), Substituted benzaldehyde and ammonium acetate. The structure of all compounds were confirmed by elemental analysis ,NMR and IR data and by melting point. In conclusion this method give some advantages such as good yield, simple procedure , low cost of chemicals and easy work up.
