In the title compound, C(36)H(29)ClN(4)O, the dihydro-pyrazole ring adopts an envelope conformation. The two quinoline ring systems (r.m.s. deviations = 0.029 and 0.018 Å) are oriented at a dihedral angle of 71.43 (4)°. One of the quinoline rings makes a dihedral angle of 65.40 (7)° with the phenyl substituent. In the crystal, mol-ecules are linked into chains along the b axis by inter-molecular C-H⋯N hydrogen bonds. In addition, C-H⋯π and π-π [centroid-centroid distance = 3.7325 (8) Å] inter-actions are observed.
