In the title compound, C 33 H 21 NO 3 , the dihedral angle between the naphthalene units is 10.85 (4)° and the pyran ring adopts a shallow boat conformation. In the crystal, C—H...N and C—H...O hydrogen bonds link the molecules, enclosing R 2 2 (16) ring motifs. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H...H, H...C/C...H, H...O/O...H and C...C interactions, at 45.8%, 27.3%, 11.2% and 9.6%, respectively.
