A variety of N-aryl-1H-indazoles and benzimidazoles were synthesized from common arylamino oximes in good to excellent yields. The product selectivity depends upon the base used in the reaction, as triethylamine promoted the formation of benzimidazoles, whereas 2-aminopyridine promoted the formation of N-arylindazoles. This method is valuable to the synthetic community because both indazoles and benzimidazoles are prevalent in pharmaceuticals.
