A novel approach to perform C−H/C−H functionalization at the C6 position of 7-azaindazoles is reported. This method employs regioselective oxidative arylation, facilitated by N-oxide activation. By utilizing this technique, precise and innovative synthesis of C6-arylated 7-azaindazoles using various substituted arenes and heteroarenes is achieved.
