Used in pharmaceutical synthesis as an intermediate in the preparation of biologically active compounds, particularly kinase inhibitors. The boronic ester group enables Suzuki-Miyaura cross-coupling reactions, allowing for efficient construction of complex molecules in drug discovery. The tert-butyl carbamate (Boc) protected amine facilitates selective amine functionalization and improves compound stability during multi-step syntheses. Commonly employed in the development of targeted therapies, including anticancer agents.
