The title compound, C19H14F3NO2, crystallizes in the keto–amine tautomeric form, with a strong intramolecular N—H
O hydrogen bond. The molecule is almost planar; the dihedral angle between the naphthalene ring system and the benzene ring is 4.60 (7)°. In the crystal, molecules are linked into chains along the c axis by C—HO hydrogen bonds. The F atoms of the trifluoromethyl group are disordered over two positions with refined site occupancies of 0.668 (9) and 0.332 (9).

In the title compound, C18H15N5O2S, a weak intramolecular C—HS hydrogen bond results in a small dihedral angle of 3.71 (9)° between the methylphenyl and triazole rings, which, in turn, form dihedral angles of 80.09 (8) and 77.32 (8)°, respectively, with the benzoxazolone mean plane. In the crystal, N—HO hydrogen bonds link molecules into chains along [001], and weak C—HN hydrogen bonds and π–π interactions between the five- and six-membered rings [centroid–centroid distances = 3.5074 (11) and 3.616 (1) Å] consolidate the crystal packing.
