The synthesis of a series of 2-aryl-2H, 4H-imidazo[4,5-d][1,2,3]triazoles is reported. These compounds are obtained in moderate to good yield by reaction of triethyl N-1-ethyl-2-methyl-4-nitro-1H-imidazol-5yl phosphoramidate with aryl isocyanates.
Condensation of 4-methylsulfonylaniline with aryl aldehyde in ethanol-tetrahydrofuran afforded the imino compound 3. 1,3-Cycloaddtion of diazomethane with compound 3 followed by oxidazation of the triazoline 4 with potassium permanganate gave 1-(4-methylsulfonylphenyl)-5-aryl-1,2,3-triazoles 5. Simi
