(Received 24 July 2013; accepted 20 August 2013; online 23 August 2013)

In the title compound, C15H15N3O2S, the fused ring system is close to planar, the largest deviation from the mean plane being 0.030 (2) Å, and makes a dihedral angle of 48.84 (9)° with the benzene ring belonging to the methyl­benzene­sulfonamide moiety. In the crystal, mol­ecules are ­connected through N—H⋯N hydrogen bonds and weak C—H⋯O contacts, forming a two-dimensional network parallel to (001).

Comment top

Sulfonamide derivatives are well known pharmaceutical agents since this group has been the main functional part of many drug structures, due to stability and tolerance in human beings. These compounds exhibit a wide range of biological activities, such as anticancer, anti-inflammatory, and antiviral functions (Bouissane et al., 2006; Mustafa et al., 2012; Lopez et al., 2010). The present work is a continuation of the investigation on sulfonamide derivatives published recently by our team (Abbassi et al., 2012, 2013).

The molecule of 4-methyl-N-(1-methyl-1H-indazol-5-yl)-benzenesulfonamide is built up from two fused five- and six-membered rings (N2/N3/C1 to C7) linked to the benzenesulfonamide group, as shown in Fig. 1. The fused rings system is almost planar, with the maximum deviation of 0.030 (2) Å arising from atom C1. Moreover, the dihedral angle between the indazole system and the plan through the atoms forming the benzene ring (C9 to C14) is 48.84 (9)°.

In the crystal, the molecules are interconnected through C3—H3···O2ii weak contacts and N1—H1···N2i hydrogen bonds, forming a two-dimensional network (Fig. 2 and Table 2; symmetry codes: (i) -x + 1, y + 1/2, -z + 1/2; (ii) x + 1, y, z).

Experimental top

A mixture of 1-methyl-5-nitroindazole (1.22 mmol) and anhydrous SnCl2 (1.1 g, 6.1 mmol) in 25 ml of absolute ethanol was heated at 333 K for 6 h. After reduction, the starting material disappeared, and the solution was allowed to cool down. The pH was made slightly basic (pH 7–8) by addition of 5% aqueous potassium bicarbonate before extraction with ethyl acetate. The organic phase was washed with brine and dried over magnesium sulfate. The solvent was removed to afford the amine, which was immediately dissolved in pyridine (5 ml) and then reacted with 4-methylbenzenesulfonyl chloride (1.25 mmol) at room temperature for 24 h. After the reaction mixture was concentrated in vacuo, the resulting residue was purified by flash chromatography (eluted with ethyl acetate/hexane 1:9). The title compound was recrystallized from acetone.

Refinement top

H atoms were located in a difference map, but C-bound H atoms were placed in idealized positions and treated as riding, with C—H = 0.96 Å, and C—H = 0.93 Å for methyl and aromatic CH, respectively. Atom H1 was first refined freely, and then fixed (N1—H1 = 0.8759 Å). All H atoms were refined with isotropic displacement parameters fixed as Uiso(H) = 1.2Ueq(C-aromatic, NH) or Uiso(H) = 1.5Ueq(C-methyl).
