Description

Ethyl 6-chloro-1H-pyrazolo[3,4-b]pyridine-4-carboxylate is a bench-stable heterocyclic ester featuring a chlorinated pyrazolopyridine core. This electron-deficient scaffold integrates readily into synthetic sequences requiring nitrogen-rich, planar architectures. The ester functionality enables straightforward derivatization, while the chlorine atom serves as a site for palladium-catalyzed cross-coupling reactions.

Application

Ethyl 6-chloro-1H-pyrazolo[3,4-b]pyridine-4-carboxylate serves as a versatile building block for the synthesis of pyrazolopyridine-based scaffolds. The chloro group at the C6 position enables facile palladium-catalyzed cross-coupling reactions, while the ester functionality supports hydrolysis and derivatization. Its bench-stable nature and compatibility with diverse functional groups facilitate efficient access to complex heterocycles relevant in medicinal chemistry and agrochemical research.
