【 摘 要 】

In the title compound, C21H16N2O2, the meth­oxy­benzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 83.62 (5)°. The 4H-pyran ring fused with the naphthalene ring system is almost planar [maximum deviation = 0.033 (1) Å]. In the crystal, mol­ecules are linked into inversion dimers by pairs of N—H⋯N hydrogen bonds. N—H⋯O hydrogen bonds connect the dimers, forming a helical supra­molecular chain along the a-axis direction. The crystal packing also features C—H⋯π inter­actions.
