title: (2S)-Methyl 2-(4-chloro-benzene-sulfon-amido)-4-(methyl-sulfan-yl)butanoate.
abstract: The enanti-omerically pure title compound, C(12)H(16)ClNO(4)S(2), contains a pyramidal N atom with an S-N bond length of 1.6306 (15) Å. Mol-ecules are linked to form chains parallel to the a axis by classical N-H⋯O hydrogen bonding involving a sulfonyl O atom, supported by three weak C-H⋯X inter-actions. (X = S, O).
