The synthesis of a series of 2-aryl-2H,4H-imidazo[4,5-d][l,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-5-yl phosphoramidate with aryl isocyanates. (C) 2000 Elsevier Science Ltd. All rights reserved.
