Abstract: In the crystal structure of the title compound, C15H20N2O3S, the hydroxy group is involved in the formation of O-H...N hydrogen bonds, which link two molecules into a centrosymmetric dimer. Weak C-H...O hydrogen bonds further link these dimers into chains propagating along the a axis. The crystal packing exhibits [pi]-[pi] interactions between the five- and six-membered rings of neighbouring molecules [centroid-centroid distance = 3.819 (2) Å] and short intermolecular S...S contacts of 3.495 (1) Å.
