Abstract
We show that N3-MEM-protected imidazo [4, 5-b] pyridines undergo efficient C2- functionalisation via direct C–H arylation. Twenty-two substituted imidazo [4, 5-b] pyridines are prepared and iterative, selective elaboration of functionalised imidazo [4, 5-b] pyridines gives 2, 7-and 2, 6-disubstituted derivatives in goo
