In the title molecule, C20H19NO3S, the dihedral angle between the phenyl rings is 48.93 (18)°, and they make dihedral angles of 38.37 (17) and 86.50 (19)° with the benzene ring. A weak intramolecular C—H⋯O interaction might stabilize the molecular conformation. In the crystal, weak π–π stacking interactions between the benzene rings [centroid–centroid distance = 3.774 (2) Å] may help to establish the packing.

A mixture of N-(2-methoxyphenyl)benzenesulfonamide (1.24 g, 5.0 mmol), sodium hydride (0.24 g, 10 mmol) and N,N-dimethylformamide (10 ml) was stirred at room temperature for 45 min and the benzyl chloride (0.64 g, 5.0 mmol) was added. The stirring was continued further for a period of 3 h and the contents were poured over crushed ice. The precipitated product was isolated, washed and re-crystallized from methanolic solution to yield light violet blocks of (I). Yield 65%.
All H atoms were positioned geometrically with C—H = 0.93–0.97 Å and allowed to ride on their parent atoms, with Uiso(H) = 1.2 or 1.5Ueq(C).
Sulfonamides are found in a number of natural as well as synthetic compounds. These molecules are considered as biologically very acitive compounds (Ozbek et al., 2007, Parari et al., 2008). As a contribution to a structural study of sulfonamide derivatives (Asiri et al., 2009, Aziz-ur-Rehman et al., 2010) here, we report the title compound (I).
In the molecule of (I), (Fig. 1), the bond lengths and bond angles are within the expected ranges. The geometry around S1 atom is distorted from a regular tetrahedron. The largest deviation is in the angle O2—S1—O1 [118.92 (12)°].
The dihedral angle between the phenyl rings (C1–C6) and (C15–C20) is 48.93 (18)° and they make dihedral angles of 38.37 (17) and 86.50 (19)°, respectively, with the benzene ring (C7–C12).
In the π–π stacking interactions [Cg2···Cg2 (1 - x, -y, 1 - z) = 3.774 (2) Å; Cg2 is a centroid of the C7–C12 benzene ring] contribute to the stabilization of the Fig. 2 show the packing diagram of (I) down the b axis.

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Sulfonamides are found in a number of natural as well as synthetic compounds. These molecules are considered as biologically very acitive compounds (Ozbek et al., 2007, Parari et al., 2008). As a contribution to a structural study of sulfonamide derivatives (Asiri et al., 2009, Aziz-ur-Rehman et al., 2010) here, we report the title compound (I).
In the molecule of (I), (Fig. 1), the bond lengths and bond angles are within the expected ranges. The geometry around S1 atom is distorted from a regular tetrahedron. The largest deviation is in the angle O2—S1—O1 [118.92 (12)°].
The dihedral angle between the phenyl rings (C1–C6) and (C15–C20) is 48.93 (18)° and they make dihedral angles of 38.37 (17) and 86.50 (19)°, respectively, with the benzene ring (C7–C12).
In the crystal structure, there is no classic hydrogen bonds. Weak intramolecular C—H···O interactions stabilize the molecular conformation. π–π stacking interactions [Cg2···Cg2 (1 - x, -y, 1 - z) = 3.774 (2) Å; Cg2 is a centroid of the C7–C12 benzene ring] contribute to the stabilization of the crystal structure. Fig. 2 show the packing diagram of (I) down the b axis.
