Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure enables the development of agents with enhanced metabolic stability due to the presence of fluorine atoms. Commonly employed in the preparation of potent enzyme inhibitors and receptor modulators, especially in programs focused on serotonin and dopamine pathways. The tert-butyl protecting group facilitates selective reactions in multi-step syntheses, making it valuable in medicinal chemistry for constructing complex nitrogen-containing scaffolds.
