Abstract: In the title compound, C23H22N4O4, the essentially planar [maximum deviation = 0.022 (1) Å] benzimidazole ring system forms dihedral angles of 86.16 (7) and 37.38 (6)°, respectively, with the imidazole and benzene rings. The dioxolane ring adopts an envelope conformation with the methylene C atom at the flap. In the crystal, C-H...O and C-H...N interactions link the molecules into a ribbon along the a axis. The crystal packing is further stabilized by weak [pi]-[pi] stacking interactions [centroid-centroid distances = 3.5954 (8) and 3.7134 (8) Å] and C-H...[pi] interactions.
