R. Zheng, W. Zhang, L.-T. Yu, S.-Y. Yang and L. Yang

Abstract: The molecule of the title compound, C₁₀H₁₀N₂O₂S, is essentially planar, except for the ethyl group, which is twisted away from the carboxyl plane by -90.5 (3)°. In the crystal structure, molecules are linked into a zigzag sheet propagating along the b axis by intermolecular N-HO and N-HN hydrogen bonds.
