Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization of the pyridine ring, making it valuable in medicinal chemistry for constructing drug candidates targeting cancer, inflammation, and central nervous system disorders. The tert-butoxycarbonyl (Boc) protecting group stabilizes the amine during reactions and can be easily removed under mild acidic conditions, enabling stepwise assembly of complex molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to form carbon-nitrogen or carbon-carbon bonds in advanced intermediates.
