چکیده
The title compound, C(14)H(11)NO(2)S(2), was synthesized by reaction of 2-(1,3-dithio-lan-2-yl-idene)-3-oxo-N-phenyl-butanamide with N,N'-dimethyl-formamide dimethyl acetal in N,N'-dimethyl-formamide. The mol-ecule exhibits a V-shaped conformation in the crystal, with a dihedral angle of 65.9 (2)° between the benzene and pyridine rings. In the crystal. C-H⋯O and C-H⋯S interactions are observed. Two C atoms of the dithiolane ring are disordered with occupancies in the ratio 0.541 (13)/0.459 (13).
