ABSTRACT
In the title compound, C(23)H(20)FNO(4), 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) Å], with a dihedral angle of 83.79 (6)°. The pyran ring adopts a flattened boat conformation. The meth-oxy group is slightly twisted from the attached benzene ring of the 4H-benzo[h]chromene moiety [C-O-C-C = -2.1 (2)°]. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯F hydrogen bonds into a layer parallel to the bc plane. The crystal packing also features C-H⋯π inter-actions.
