چکیده
The title compound, C(8)H(10)N(2)O(2)S, was prepared by the reaction of 2-cyano-3,3-bis-(methyl-sulfan-yl)acrylate and 2-amino-ethanethiol at 350 K. The mol-ecular structure and packing are stabilized by N-H⋯O hydrogen-bond inter-actions. All the non-H atoms are nearly in the same plane with the maximum deviation being 0.08 Å.
