N,N-Diethyl-2-(4-methyl-benzene-sulfonamido)-benzamide

N-(2-Amino-5-chloro-phen-yl)-2-bromo-benzene-sulfonamide

In the title compound, C₁₂H₁₀BrClN₂O₂S, the sulfonamide group adopts a staggered conformation about the N—S bond [the C—S—N—H torsion angle is 97 (3)°] with the N-atom lone pair bis­ecting the O=S=O angle. For the C(Ar)—S bond, the ortho-substituted C atom bis­ects one of O=S–N angles [the C—C—S—N torsion angle is −57.7 (3)°]. The mean planes of the aromatic rings form a dihedral angle of 75.1 (1)°. In the crystal, mol­ecules form inversion dimers through pairs of N—H⋯NH₂ hydrogen bonds. The mol­ecules are further consolidated into layers along the bc plane by weaker N—H⋯O inter­actions.
