Triazolopyridines have found various applications as pharmaceuticals, agrochemicals, or optical materials. Consequently, the introduction of various functionalities at specific sites of this heterocyclic framework is of great importance. In this regard, we report the development of a site-selective Suzuki–Miyaura reactions leading to substituted triazolopyridines at positions 6 and 8. Under optimized conditions, the respective products have been obtained with high selectivity and yield.
