In the title compound, C 23H 22N 4O 4, 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 π-π stacking interactions [centroid-centroid distances = 3.5954(8) and 3.7134(8) Å] and C-H··· π interactions.
