In the title molecule, C20H17Cl2NO, the central heterocyclic ring adopts a flattened boat conformation. The dihedral angles between the planar part of this central heterocyclic ring [maximum deviation = 0.004 (1) A] and the two almost planar side-chain fragments [maximum deviations = 0.015 (1) and 0.019 (1) A], that include the aromatic ring and bridging atoms, are 18.1 (1) and 18.0 (1)degrees. In the crystal, pairs of weak intermolecular C-H...O hydrogen bonds link molecules into inversion dimers that form stacks along the a axis. The structure is further stabilized by weak intermolecular C-H...pi interactions involving the benzene rings.
