(Received 27 October 2010; accepted 28 October 2010; online 6 November 2010)

The mol­ecule of the title compound, C15H17NO2S, has a C—S—N—C torsion angle of 71.4 (2)°, and the dihedral angle between the benzene rings is 82.83 (16)°. In the crystal, mol­ecules are linked into chains along the b axis via C—H⋯O hydrogen bonds. A C—H⋯π inter­action is also present in the crystal structure.

Comment top

Sulfonamides have extensively been reported for their wide variety of pharmacological activities such as antibacterial (Maren, 1976) and diuretic (Boyd, 1988). The present structure is continuous to our previous reported derivative of sulfonamide (Khan, Ahmad, Arshad et al. et al., 2010; Khan, Ahmad, Sharif et al., 2010).

In the title molecule (I), (Fig. 1), the molecule has a C4—S1—N1—C9 torsion angle of 71.4 (2)°. The dihedral angle between the sulfonyl benzene ring (C1–C6) and the phenyl ring (C10–C15) is 82.83 (16)°. In the structure, molecules are linked into chains along the b axis via C—H···O hydrogen bonding (Table 1, Fig. 2). In the structure, there is a C—H···π interaction (Table 1).

Experimental top

A mixture of N-benzyl-4-methylbenzenesulfonamide (0.5 g, 2.02 mmol) and sodium hydride (0.2 g, 8.333 mmol) in N,N-dimethylformamide (10 ml) was stirred at room temperature for 30 min followed by the addition of methyl iodide (0.25 ml, 2.02 mmol). After the consumption of reactants (as monitored by TLC), the contents were poured over crushed ice. The precipitated product was isolated, washed, dried and recrystallized from chloroform solution to yield colourless blocks of title compound.

Refinement top

All H atoms were positioned geometrically with C—H = 0.93–0.97 Å and treated as riding on their parent atoms, with Uiso(H) = 1.2 or 1.5Ueq(C).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
