5 mM of p-toluidine was dissolved in 20 ml of distilled water then 5 mM of ethyl iodide was added. The reaction mixture was stirred properly and 5 mM of benzenesulfonyl chloride was added. The mixture was stirred for about 1–2 h and the pH was maintained 8–10 using 3% Na2CO3 solution. The reaction was monitored by TLC. The product obtained was filtered and the precipitate was washed with distilled water, dried and recrystallized using methanol.
All H atoms were geometrically positioned and refined using a riding model with C—H = 0.93–0.97 Å. The Uiso(H) values were constrained to be 1.5Ueq(methyl-C) or 1.2Ueq(other C atoms). In the final
one low angle reflection, 0 0 2, evidently effected by the beam stop was omitted.Data collection: APEX2 (Bruker, 2007); cell

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. |

Sulfonamides commonly named as Sulfa drugs are the medicines capable of controlling the bacterial infections (Laurence, 2009). The phenolic azo- dyes derived from the sulfonamides have the therapeutic potentialities and special mode of action against the acute bacterial infections (Korolkovas, 1988). Some benzenesulfonamide are evaluated for their in vitro antitumor activity (Faidallah et al., 2007). Hemorrhagic colitis (i.e. swollen of Colon and diarrhea) can be the direct result of the toxic effect of the ingested sulfonamide but with the withdrawal of the sulfonamides from the body, the symptoms subsided and body returns to its normal activity (Gauss & Weinstein, 1946) As part of our ongoing studies of the effect of substitutions on the structures of N-(aryl)-arylsulfonamides (Ahmad et al., 2011), we synthesized the title compound, (I), and report herein its crystal structure.
As shown in Fig. 1, the title molecule is twisted at the S—N bond with the C10—S1—N1—C5 torsion angle of 73.90 (14)°, compared to the values of 80.2 (3)° (molecule 1) and -79.4 (3)° (molecule 2) in N-ethyl-4-methyl-N-(3-methylphenyl)benzenesulfonamide (II) (Ahmad et al., 2011), -58.4 (2) and -48.3 (2)° (molecule 1) and -75.7 (3)° (molecule 2), in the two molecules of 2,4-dimethyl-N-(4-methylphenyl)benzenesulfonamide (III) (Nirmala et al., 2011). The phenyl and benzene rings in (I) are tilted relative to each other by 36.76 (11)°, compared to the values of 35.3 (2)° (molecule 1) and 42.5 (2)° (molecule 2) in (II), and 72.0 (1)° (molecule 1) and 78.3 (1)° (molecule 2) in (III). No classical hydrogen bonds are observed in the crystal structure. The crystal packing of (I) is shown in Figs. 2 & 3 down the a and b axes, respectively.
