Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective cross-coupling reactions, making it valuable in constructing complex molecules for drug discovery. Commonly employed in palladium-catalyzed reactions such as Suzuki or Heck couplings to introduce the pyridine moiety into target molecules. Also utilized in the preparation of protease inhibitors and antiviral agents due to its ability to mimic natural heterocyclic components in biological systems.
