In the title compound, C(22)H(17)BrN(2)O(2), the benzimidazole ring system is essentially planar, with a maximum deviation of 0.017 (1) Å, and forms dihedral angles of 27.79 (6) and 64.43 (6)° with the phenyl and bromo-substituted benzene rings, respectively. In the crystal, mol-ecules are linked into one-dimensional chains along the a axis by weak C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions are also present.
