In the title compound, C15H15NO3S, the 2-methylphenyl ring bonded to the sulfonyl group is disordered with site-occupation factors of 0.75:0.25. The dihedral angles between the two aromatic rings are 67.6 (1) and 69.2 (1)° for the major and the minor occupied sites, respectively. In the crystal, molecules are linked into centrosymmetric dimers by pairs of N—H⋯O hydrogen bonds.

The title compound was prepared by refluxing a mixture of 2-methylbenzoic acid, 2-methylbenzenesulfonamide and phosphorous oxy chloride for 5 h on a water bath. The reaction mixture was cooled and poured into ice cold water. The resulting solid, 2-methyl-N-(2-methylbenzoyl)benzenesulfonamide, was separated, washed thoroughly with water and then dissolved in sodium bicarbonate solution. The compound was later reprecipitated by acidifying the filtered solution with dilute HCl. The filtered and dried compound was recrystallized to the constant melting point.
Prism like colourless single crystals of the title compound were grown by slow evaporation of its toluene solution at room temperature.
The H atom of the NH group was located in a difference map and restrained to N—H = 0.86 (1) %A. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.96 Å. All H atoms were refined with isotropic displacement parameters set to 1.2 times of the Ueq of the parent atom.
The methylphenyl ring with atoms C1, C2, C3, C4, C5, C6 and C14 is disordered over two sites related by a twofold rotation. The corresponding site-occupation factors were fixed to 0.75:0.25 and their corresponding bond distances in the disordered groups were restrained to be equal.
Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As part of a study of the effect of ring and the side chain substituents on the crystal structures of N-aromatic ═O segment of the structure is anti to the C═O bond, similar to that observed in 2-methyl-N-(3-methylbenzoyl)benzenesulfonamide (II) (Gowda et al., 2010a), 2-methyl-N-(4-methylbenzoyl)- benzenesulfonamide (III) (Gowda et al., 2010b) and 2-chloro-N-(2-chlorobenzoyl)benzenesulfonamide (IV) (Suchetan et al., 2010).
(Gowda et al., 2010a,b; Suchetan et al., 2010), in the present work, the structure of 2-methyl-N-(2-methylbenzoyl)benzenesulfonamide (I) has been determined (Fig.1). The conformation of the N—H bond in the S—NH—CThe conformation of the C=O bond is syn to the ortho-methyl group in the benzoyl ring, similar to that observed between the C=O bond and the ortho-Cl in (IV), but contrary to the anti conformation observed between the C=O bond and the meta-methyl group in (II).
The molecules are twisted at the S atom with the torsional angles of 57.8 (2)° (major component) and 78.6 (2)° (minor component), compared to the values of -66.2 (3)° in (II), -53.1 (2)° and 61.2 (2)° in the two molecules of (III), and 66.5 (3)° in (IV),
The dihedral angles between the sulfonyl benzene ring and the S—NH—C═O segment are 82.7 (1)° (major component) and 85.1 (3)° (minor component), compared to the values of 83.1 (1) in (II), 86.0 (1)° and 87.9 (1)° in the two molecules of (III), and 86.9 (1) in (IV)
The dihedral angle between the sulfonyl and the benzoyl benzene rings are 67.6 (1)° and 69.2 (1)° in the major and the minor components, respectively, compared to the values of 74.8 (1) in (II), 88.1 (1)° (molecule 1) and 83.5 (1)° (molecule 2) of (III), and 76.9 (1) in (IV).
The molecules are linked into chains by N—H···O(S) hydrogen bonds (Table 1 and Fig. 2).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) 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. |

Diaryl acylsulfonamides are known as potent antitumor agents against a broad spectrum of human tumor xenografts in nude mice. As part of a study of the effect of ring and the side chain substituents on the crystal structures of N-aromatic sulfonamides (Gowda et al., 2010a,b; Suchetan et al., 2010), in the present work, the structure of 2-methyl-N-(2-methylbenzoyl)benzenesulfonamide (I) has been determined (Fig.1). The conformation of the N—H bond in the S—NH—C═O segment of the structure is anti to the C═O bond, similar to that observed in 2-methyl-N-(3-methylbenzoyl)benzenesulfonamide (II) (Gowda et al., 2010a), 2-methyl-N-(4-methylbenzoyl)- benzenesulfonamide (III) (Gowda et al., 2010b) and 2-chloro-N-(2-chlorobenzoyl)benzenesulfonamide (IV) (Suchetan et al., 2010).
The conformation of the C=O bond is syn to the ortho-methyl group in the benzoyl ring, similar to that observed between the C=O bond and the ortho-Cl in (IV), but contrary to the anti conformation observed between the C=O bond and the meta-methyl group in (II).
The molecules are twisted at the S atom with the torsional angles of 57.8 (2)° (major component) and 78.6 (2)° (minor component), compared to the values of -66.2 (3)° in (II), -53.1 (2)° and 61.2 (2)° in the two molecules of (III), and 66.5 (3)° in (IV),
The dihedral angles between the sulfonyl benzene ring and the S—NH—C═O segment are 82.7 (1)° (major component) and 85.1 (3)° (minor component), compared to the values of 83.1 (1) in (II), 86.0 (1)° and 87.9 (1)° in the two molecules of (III), and 86.9 (1) in (IV)
The dihedral angle between the sulfonyl and the benzoyl benzene rings are 67.6 (1)° and 69.2 (1)° in the major and the minor components, respectively, compared to the values of 74.8 (1) in (II), 88.1 (1)° (molecule 1) and 83.5 (1)° (molecule 2) of (III), and 76.9 (1) in (IV).
The molecules are linked into chains by N—H···O(S) hydrogen bonds (Table 1 and Fig. 2).
