Abstract

In the title compound, C17H19NO2S2, the 2H-chromene ring system is almost planar, with a maximum deviation of 0.044 (2) Å, and the pyrrolidine ring adopts an envelope conformation. The dihedral angle between the 2H-chromene system and the planar part of the pyrrolidine ring is 83.65 (8)°. A weak intra­molecular C—H⋯S hydrogen bond occurs. The crystal structure features C—H⋯O hydrogen bonds and π–π inter­actions, with a centroid–centroid distance of 3.5728 (16) Å.
