In the title compound, C38H31Cl4N3O·C3H6O, the 3,7-diaza-bicycle exists in a chair–boat conformation. The 4-chloro­phenyl groups attached to the chair form are equatorially oriented at an angle of 18.15 (3)° with respect to each other, whereas the 4-chloro­phenyl groups attached to the boat form are oriented at an angle of 32.64 (3)°. In the crystal, mol­ecules are linked by N—H⋯π and C—H⋯O inter­actions.
