In the title compound, C(16)H(22)ClNS, the nine-membered 2,3-dihydro-1,3-benzothia-zole ring system is essentially planar, with a maximum deviation of 0.025 (2) Å for the N atom. Its plane is almost perpendicular to the main plane of the substituted cyclo-hexane ring, which adopts a chair conformation. In the crystal, the molecules are linked by C-H⋯π inter-actions.
