In the molecule of the title compound, C16H17N3O2, the planar benzimidazole ring system [maximum deviation = 0.013 (1) angstrom] is oriented at a dihedral angle of 75.32 (4)degrees with respect to the furan ring. An intramolecular C-H center dot center dot center dot O interaction results in the formation of a planar six-membered ring [maximum deviation = 0.019 (15) angstrom], which is oriented at a dihedral angle of 1.91 (3)degrees with respect to the adjacent furan ring. In the crystal structure, intermolecular C-H center dot center dot center dot N interactions link the molecules into centrosymmetric R-2(2)(18) dimers. In addition, the structure is stabilized by pi-pi contacts between the imidazole rings [centroid-centroid distance = 3.5307 (8) angstrom] and weak C-H center dot center dot center dot pi interactions.
