Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. The iodine atom allows for further functionalization via cross-coupling reactions such as Suzuki or Heck couplings, enabling the construction of complex pyridine-based structures. The Boc-protected amine group provides stability during reactions and can be selectively deprotected to introduce amine functionality when needed. Commonly employed in medicinal chemistry for lead optimization and in the preparation of drug candidates targeting cancer and inflammatory diseases.
