Abstract: In the racemic title compound, C22H21NO3, the nitrogen-containing ring of the pyranoquinoline moiety adopts a slightly distorted half-chair conformation and the oxygen-containing ring adopts a slightly distorted chair conformation. The benzene rings make a dihedral angle of 84.97 (8)°. In the crystal, weak C-H...O interactions link the molecules into chains extending along the a-axis direction.
