Abstract: In the title compound, C₁₃H₁₅NO₃S, the sole classical hydrogen-bond donor is involved in an intramolecular O-HN hydrogen bond. In the crystal structure, pairs of molecules related by inversion centres are linked by pairs of weak intermolecular C-HO interactions; these centrosymmetric pairs are, in turn, linked further by weak intermolecular C-HO interactions, forming two-dimensional sheets oriented parallel to (101).
