The asymmetric unit of the title compound, C(22)H(20)N(2), contains two crystallographically independent mol-ecules in which the planar benzimidazole ring systems are oriented with respect to the adjacent tolyl rings at dihedral angles of 47.08 (8)/76.85 (8) and 39.52 (9)/87.49 (9)°, while the dihedral angles between the tolyl rings are 73.99 (3) and 81.51 (9)°. In the crystal structure, pairs of inter-molecular C-H⋯N inter-actions link one of the asymmetric mol-ecules into centrosymmetric dimers through R(2) (2)(8) ring motifs.
