The cyclo-hexene ring in the title compound, C(19)H(23)Cl(2)NOS(2), adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.630 (2) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.020 Å). The mol-ecular conformation is stabilized by an intra-molecular N-H⋯S hydrogen bond.
