Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structural features, including the trifluoromethylphenyl and pyrrolidine moieties, make it valuable in medicinal chemistry for enhancing metabolic stability and binding affinity. Commonly employed in the preparation of potent enzyme inhibitors and receptor modulators, especially in research focused on serotonin and dopamine receptor subtypes. The ester groups allow for further functionalization, enabling the construction of complex drug-like molecules in late-stage synthesis.
