Abstract

In the title compound, C11H16N2O3S, the S atom has a distorted tetra­hedral geometry [maximum deviation: O—S—O = 119.48 (15)°]. The dihedral angles between the benzene ring and its propyl­sulfonamide and methyl­amide substituents are 71.8 (2) and 5.8 (1)°, respectively. In the crystal, mol­ecules are linked by Nm—H⋯Os (m = methyl­amide and s = sulfonamide) hydrogen bonds, forming C(8) chains along the a axis. The two mol­ecule chains are connected by N—H⋯O hydrogen bonds, generating R32(18) rings. The crystal packing is further stabilized by weak inter­molecular C—H⋯O hydrogen bonds.
