4- (5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl) pyrimidin-2-amine

4- (5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl) pyrimidin-2-amine is a brominated pyrrolopyridine-based scaffold designed for advanced medicinal chemistry and kinase inhibitor development. Its 7-azaindole (pyrrolopyridine) core serves as a purine bioisostere capable of occupying ATP-binding pockets across diverse kinases. The bromine substituent at the 5-position offers both electronic tuning and a versatile handle for cross-coupling reactions, enabling rapid SAR exploration. The 2-aminopyrimidine moiety further supports hinge-binding interactions, collectively making 4- (5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl) pyrimidin-2-amine a valuable starting point for generating FGFR-targeted inhibitors and other kinase-directed therapeutics.
