Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure supports the construction of complex heterocyclic systems found in drug candidates targeting neurological disorders and cancer. The tert-butyl ester group facilitates protection during multi-step syntheses, allowing selective reactions at other functional sites. Commonly employed in medicinal chemistry for optimizing lead compounds due to its favorable reactivity and stability profile.
