title: Ethyl 4-(4-chloro-phen-yl)-2-methyl-5-oxo-5,6,7,8-tetra-hydro-quinoline-3-carboxyl-ate.
abstract: In the title compound, C19H18ClNO3, the non-aromatic part of the fused ring system adopts an envelope conformation with the central methyl-ene C atom as the flap. The dihedral angle between the pyridine and benzene rings is 56.98 (3)°. In the crystal, mol-ecules are linked into double layers parallel to (100) by a network of weak C-H⋯O inter-actions.
