Abstract: 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.
