In the title compound, C(24)H(25)N(3)O(4), the pyrrolidine ring adopts an envelope conformation while the pyrrolidine-2'',5''-dione ring adopts a twist conformation. The indoline unit is planar [maximum deviation of -0.050 (9) Å] and forms a dihedral angle of 40.36 (4)° with the methoxy-phenyl ring. Intra-molecular C-H⋯O hydrogen bonds are observed. In the crystal, mol-ecules are linked into a two-dimensional network parallel to the ab plane by inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
