In the title mol-ecule, C(27)H(26)Cl(2)N(2)O(2), the chloro-substituted benzene rings make dihedral angles of 83.29 (9) and 80.81 (9)° with the benzene ring of the tetra-hydro-quinoline group. The dihedral angle formed by the two chloro-substituted benzene rings is 40.87 (12)°. The six-membered N-containing ring is in a half-chair conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers.
