Abstract

An effective and simple method for the one-pot synthesis of 4,6-diaryl-2-(2-aryl-4,5-diphenyl-1H-imidazol-1-yl)pyrimidines 13-24 from substituted 2-amino pyrimidine 1-12, benzil, substituted aromatic aldehyde and ammonium acetate in methanol by using ceric ammonium nitrate (CAN) as catalyst has been described. This CAN catalyzed reactions are carried out at a temperature of 70-75°C and give very high yields in a lesser reaction time. All the synthesized compounds have been characterized by elemental analysis, FT-IR, 1H NMR 13C NMR and MS spectral data. All the newly synthesized compounds are tested for their in vitro antimicrobial activity against selected clinically isolated bacterial and fungal strains by disc diffusion and minimum inhibitory concentration method.
