In the title compound, C16H15F3N2O4, the relative stereochemistry of the four stereogenic C atoms has been determined. The carboxymethyl and 2-(trifluoromethyl)phenyl substituents of the pyrrolidine cycle have a cis mutual arrangement. The five-membered saturated azacycle adopts an envelope conformation with the N atom occupying the flap position. In the crystal, adjacent molecules are combined in centrosymmetric dimers by two weak N—HO hydrogen bonds.
