title: Methyl 4-(4-meth-oxy-phen-yl)-2-methyl-5-oxo-1,4,5,6,7,8-hexa-hydro-quinoline-3-carboxyl-ate.
abstract: In the title compound, C(19)H(21)NO(4), the dihydro-pyridine ring adopts a distorted screw-boat conformation. The fused cyclo-hexenone ring forms a slightly distorted envelope conformation. The dihedral angle between the mean planes of the benzene and heterocyclic rings is 86.1 (7)°. An intra-molecular C-H⋯O inter-action occurs. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming an infinite chain along the c axis.
