The title Schiff base, C23H27ClN2O adopts the phenol-imine tautomeric form, with an intramolecular O-H ... N hydrogen bond, which generates an S(6) ring motif. Three C atoms of the heterocyclic moiety of the hexahydropyridoquinoline unit, as well as the two methyl groups bonded to one of these C atoms, are disordered over two set of sites, with anoccupancy ratio of 0.740 (4): 0.260 (4).
