(Z)-5-[4-(Dimethyl­amino)­benzyl­idene]-2-(piperidin-1-yl)-1,3-thia­zolidin-4(5H)-one

The mol­ecules of the title compound, C₁₇H₂₁N₃OS, are characterized by a wide C-C-C angle at the methine C atom linking the aryl and thia­zolidine rings, associated with a short repulsive intra­molecular S...H contact between atoms in these two rings. A single piperidine-arene C-H...[pi] hydrogen bond links pairs of mol­ecules into centrosymmetric dimers.
