In the title mol-ecule, C(17)H(14)N(2)OS, the mean plane of the acetamide group forms dihedral angles of 75.79 (5), 81.85 (6) and 12.32 (5)° with the two phenyl rings and the thia-zole ring, respectively. In the crystal, N-H⋯N hydrogen bonds link pairs of mol-ecules into inversion dimers with R(2) (2)(8) ring motifs. The crystal packing is further stabilized by C-H⋯π inter-actions and by π-π inter-actions with a centroid-centroid distance of 3.6977 (5) Å.
