In the title compound, C17H22FNO4, the pyrrolidine ring adopts an envelope conformation with the disordered com­ponents of the methylene C atom, with site occupancies of 0.896 (7) and 0.104 (7), being the flap on either side of the mean plane involving the other atoms of the ring. The carb­oxy­lic acid group forms dihedral angles of 72.06 (11) and 45.44 (5)° with the N-tert-but­oxy­carbonyl group and the 2-fluoro­benzyl group, respectively. In the crystal, two-dimensional layers of mol­ecules parallel to (001) are built through an R44(23) motif generated via O—H...O, C—H...O and C—H...F inter­actions, and an R22(11) motif generated by C—H...O and C—H...F inter­actions.
