In the title compound, C 23H 24N 4O 5, the essentially planar benzimidazole ring system [maximum deviation = 0.008(2) Å] forms a dihedral angle of 39.22(7)° with the attached nitrobenzene ring. The pyrrolidin-2-one ring adopts an envelope conformation with a C atom as the flap. In the crystal, molecules are connected by C-H···O interactions, forming sheets propagating in (011). The crystal packing also features weak π-π stacking interactions [centroid-centroid = 3.6746(12) Å].
