Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex nitrogen-containing heterocycles. The bromine atom allows for further functionalization via cross-coupling reactions, enabling the introduction of diverse substituents during drug discovery efforts. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to its structural rigidity and favorable steric properties.
