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