Abstract: In the title compound, C15H14ClNO2S2, the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.0133 (10) Å. Three C atoms and their attached H atoms of the pyrrolidine ring are disordered [occupany ratio 0.874 (7):0.126 (7)] with both disorder components adopting a twisted conformation. The dihedral angle between the 2H-chromene ring system and the major occupancy component of the pyrrolidine ring is 89.45 (7)°. In the crystal, inversion dimers linked by pairs of C-H...S and C-H...O inter­actions generate R22(24) and R22(10) loops, respectively. Further C-H...O hydrogen bonds link the dimers into [100] chains. C-H...[pi] inter­actions also occur and there is very weak [pi]-[pi] stacking [inter­planar spacing = 3.650 (5) Å; centroid-centroid distance = 4.095 (7) Å] between inversion-related chloro­benzene rings.
