Abstrakt: In the title compound, C14H17N3O5S, the five-membered ring is essentially planar. The substituents at the nitrogen atoms subtend a C—N—N—S torsion angle of 95.52 (6)°. The amino group forms an intramolecular hydrogen bond to a sulfonyl oxygen atom; two intermolecular hydrogen bonds from the amino group, to the other S=O group and to the oxo substituent, form a layer structure parallel to the ab plane. The structure determination confirms that the title compound is N- rather than O-alkylated. [ABSTRACT FROM AUTHOR]
