A new and highly regioselective arylation of 2-arylbenzoxazoles based on C–H activation has been developed. The results represent the first examples of palladium-catalyzeddirect ortho-arylation of 2-arylbenzoxazoles and also provide a facile route for the synthesis of complicated structures containing arylated benzoxazoles moieties.
