N-(2,5-Dimethoxy-phen-yl)-4-nitro-benzene-sulfonamide.

The title compound, C(14)H(14)N(2)O(6)S, is an inter-mediate for the synthesis of β-3-adrenergic receptor agonists. The two meth-oxy groups are approximately coplanar with the attached benzene ring [C-O-C-C = -2.7†(4) and 9.4†(4)°]. The dihedral angle between the two aromatic rings is 67.16†(12)°. An intra-molecular N-H⋯O hydrogen bond is observed. In the crystal, mol-ecules are linked into chains along the c axis by C-H⋯O hydrogen bonds.
