Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its structure supports the development of selective receptor modulators due to the presence of a trifluoromethylphenyl group and a protected pyrrolidine scaffold. Commonly employed in medicinal chemistry for optimizing drug candidates involving GPCR targets. Also utilized in the preparation of protease inhibitors and cognitive enhancers. The tert-butyl carbamate group allows for easy deprotection, enabling further functionalization in multi-step synthesis.
