In the title mol-ecule, C(16)H(14)N(2)OS(2), the benzene ring and the benzo[d]thia-zole mean plane form a dihedral angle of 75.5 (1)°. The acetamide group is twisted by 47.7 (1)° from the attached benzene ring. In the crystal, mol-ecules related by translation along the a axis are linked into chains through N-H⋯O hydrogen bonds.
