In the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bonds in the C-SO(2)-NH-C segment have gauche torsions with respect to the S=O bonds. Further, the conformation of the N-H bond is syn to the ortho-methyl group in the sulfonyl benzene ring. The torsion angle of the C-SO(2)-NH-C segment in the mol-ecule is 55.0 (2)°. The two benzene rings are tilted relative to each othe...
