title: 7-p-Tolyl-10,11-dihydro-benzo[h]furo[3,4-b]quinolin-8(7H)-one.
abstract: In the title compound, C(22)H(17)NO(2), the fused ring system is essentially planar (r.m.s. deviation = 0.021 Å) and the dihedral angle between the dihydro-pyridine and tolyl rings is 80.98 (11)°. In the crystal, the mol-ecules are linked into chains along the b axis by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds. Adjacent chains are linked by π-π inter-actions [centroid-centroid separation = 3.5748 (15) Å].
