In the title compound, C15H15NO4S, the dihedral angle between the benzene rings is 88.87 (1)°. In the crystal, adjacent molecules form inversion dimers through pairs of strong N—H⋯O hydrogen bonds, generating R22(8) loops. Two C—H⋯π interactions and an aromatic π–π interaction [centroid–centroid separation = 3.8191 (1) Å] are also observed.

The title compound was prepared by refluxing a mixture of 3-methoxybenzoic acid, 4-methylbenzenesulfonamide and phosphorous oxychloride (POCl3) for 2 h on a water bath. The resultant mixture was cooled and poured into ice cold water. The solid obtained was filtered and 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 compound obtained was filtered and later dried (Melting point: 405 K.) Colorless prisms of (I) were obtained from a slow evaporation of its ethanolic solution at room temperature.
The H atom of the NH group was located in a difference map and later refined freely. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

As a part of our continued efforts to study the crystal structures of N-(aroyl)-arylsulfonamides (Suchetan et al., 2010), we report here the crystal structure of the title compound (I) (Fig 1).
The conformation of the N—H bond in I is anti to the C=O bond in the side chain, similar to that observed in. N-(benzoyl)-4-methylbenzenesulfonamide (II, Suchetan et al., 2010). Further, the conformation between the N—H bond and the meta-methoxy group in the benzoyl ring is anti.
The dihedral angle between the methyl-substituted benzene ring (maximum deviation from mean plane: 0.007 Å for C5) and the methoxy-substituted benzene ring (maximum deviation from mean plane: 0.005 Å for C13) is 88.87 (1)°. Adjacent molecules form inversion related dimers through strong N—H···O hydrogen bonds, generating R22(8) loops (Fig 2). Two C—H···π interactions and an aromatic π-π interaction (centroid-centroid separation = 3.8191 (1) Å) are also observed in the structure (Fig 3).
