Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its functional groups allow for selective modifications, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build extended aromatic or conjugated structures. Also utilized in agrochemical research for designing novel active ingredients. The Boc-protected amine group enables controlled deprotection and further derivatization, which is advantageous in multi-step synthetic routes.
