In the title compound, C 24H 25N 3O 5, the benzimidazole and benzodioxole ring systems are each approximately planar [maximum deviations = 0.043 (1) and 0.036 (1) Å, respectively]. Their mean planes form a dihedral angle of 42.85 (4)°. The pyrrolidine ring has an envelope conformation with one of the methylene C atoms forming the flap. In the crystal, weak C-H⋯O hydrogen bonds link the molecules into a three-dimensional network. The crystal packing is further stabillized by weak π-π interactions between the benzene rings within the benzimidazole ring system [centroid-centroid distance = 3.7955 (7) Å]. A weak C-H⋯π interaction involving the benzodioxole ring is also present.
