Abstract: In the title compound, C19H18ClNO3, the non-aromatic part of the fused ring system adopts an envelope conformation with the central methylene C atom as the flap. The dihedral angle between the pyridine and benzene rings is 56.98 (3)°. In the crystal, molecules are linked into double layers parallel to (100) by a network of weak C-H...O interactions.
