Abstract: In the title compound, C21H20FN3O5, the the pyrrolidine ring makes dihedral angles of 84.91 (6) and 62.38 (7)° with the oxindole unit and the fluoro­phenyl ring, respectively. The pyrrolidine ring assumes an envelope conformation with the spiro C atom as the flap. The crystal packing features weak N-H...N and C-H...O hydrogen bonds.
