Abstract
In the title compound, C12H17NO5S, the orientations of the 2-ethyl-2-amino-3-hydroxypropanoate group and the 4-methylsulfonyl moiety towards the aromatic ring are periplanar and (−)-anticlinal, respectively. In the crystal packing, the dominant interaction is O—H⋯N hydrogen bonding, which generates a chain running along [100]. N—H⋯O and C—H⋯O interactions are also observed.
