In the title compound, C24H25N3, the benzimidazole ring system is essentially planar, with an r.m.s. deviation of 0.017 Å, and forms dihedral angles of 7.81 (5) and 87.61 (4)° with the pyridine and benzene rings, respectively. An intramolecular C—HN hydrogen bond is observed. In the crystal, molecules are stacked along the a axis by weak C—Hπ interactions.
