Abstract
In the title compound, C23H20FNO4, the fluoro-substituted benzene ring is approximately perpendicular to the mean plane of the 4H-benzo[h] chromene ring system [maximum deviation = 0.264 (1) angstrom], with a dihedral angle of 83.79 (6)degrees. The pyran ring adopts a flattened boat conformation. The methoxy group is slightly twisted from the attached benzene ring of the 4H-benzo[h] chromene moiety [C-O-C-C = -2.1 (2)degrees]. An intramolecular N-H center dot center dot center dot O hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked by N-H center dot center dot center dot O and N-H center dot center dot center dot F hydrogen bonds into a layer parallel to the bc plane. The crystal packing also features C-H center dot center dot center dot pi interactions.
