In the title compound, C17H17ClN2O2S, the o-chloro­phenyl group is almost coplanar with the thio­phene ring and the C—N bond distance indicates delocalization of π bonding across the ring systems. There are intramolecular N—H...O, N—H...Cl and C—H...O hydrogen bonds, and intermolecular C—H...O interactions.

The cyclo­hexene ring of the title compound, C17H17ClN2O2S, shows disorder, with a 60% major conformer and a 40% minor conformer. Both adopt half-chair conformations. In addition to intra­molecular N—H...N and C—H...O hydrogen bonds, there are inter­molecular N—H...O hydrogen bonds and very weak C—H...N and C—H...O inter­actions.

In the title compound, C24H24ClN2O2S, the variations in the bond lengths and angles around the N atoms indicate delocalization of the N-atom lone pair. The mol­ecular structure is stabilized by intra­molecular N—H...N, N—H...Cl, C—H...S and C—H...O hydrogen bonds.
