Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows selective functionalization in cross-coupling reactions, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in palladium-catalyzed reactions such as Suzuki or Negishi couplings to form carbon-carbon bonds in drug discovery pipelines. The silyl protecting group enhances stability and regioselectivity during multi-step syntheses.
