A simple procedure for the synthesis of 2-aroylindole derivatives comprising a one-pot CuI-catalyzed SNAr reaction of o-bromochalcones with sodium azide and subsequent intramolecular cyclization through nitrene C-H insertion has been developed. This protocol is also applicable with the 2'-bromocinnamates giving the indole-2-carboxylates.
