Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and selective receptor modulators. Its bromine functionality allows for further cross-coupling reactions, enabling the introduction of complex substituents. The tert-butoxycarbonyl (Boc) group protects the nitrogen during multi-step syntheses, ensuring selective reactivity at other sites. Commonly employed in the preparation of bioactive piperidine derivatives, including antidepressants, antipsychotics, and kinase inhibitors. Its stereochemistry is crucial for achieving desired biological activity in final drug compounds.
