title: Ethyl 2-benzene-sulfonamido-4-methyl-penta-noate.
abstract: In the title compound, C(14)H(21)NO(4)S, the O-S-O angle is 120.06 (11)°, with the S atom adopting a distorted tetra-hedral geometry. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules along the a axis, generating an infinite chain. The disordered C atoms of the isobutyl group were refined with the C-C distances restrained to 1.52 (1) Å and the occupancy ratio refined to 0.504 (3):0.496 (3).
