The asymmetric unit of the title compound, C(18)H(11)NO(2)S, contains two crystallographically independent mol-ecules. In one mol-ecule, the oxazole and thio-phene rings are oriented at dihedral angles of 17.40 (9) and 18.18 (7)° with respect to the naphthalene ring system, while the oxazole and thio-phene rings are oriented to each other at a dihedral angle of 0.86 (9)°. In the other mol-ecule, the corresponding angles are 3.05 (8), 9.62 (6) and 7.02 (8)°, respectively. In each mol-ecule, a weak intra-molecular C-H⋯N hydrogen bond links the oxazole N atom to the naphthalene group. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. π-π stacking between the oxazole and thio-phene rings, between the thio-phene and naphthalene rings, and between the oxaozole and naphthalene rings, [centroid-centroid distances = 3.811 (2), 3.889 (2), 3.697 (2) and 3.525 (2) Å] may further stabilize the crystal structure.
