In the title compound, C24H15NO2, the oxazole ring is oriented at dihedral angles of 10.09 (4) and 6.04 (4)degrees with respect to the mean planes of the naphthalene ring systems, while the two naphthalene ring systems make a dihedral angle of 4.32 (3)degrees. Intramolecular C-H center dot center dot center dot N hydrogen bonds link the oxazole N atom to the naphthalene ring systems. In the crystal, intermolecular weak C-H center dot center dot center dot O hydrogen bonds link the molecules into centrosymmetric dimers. pi-pi contacts between the oxazole and naphthalene rings and between the naphthalene ring systems [centroid-centroid distances = 3.5947 (9) and 3.7981 (9) angstrom] may further stabilize the crystal structure. Three weak C-H center dot center dot center dot pi interactions also occur.
