In the title compound, C21H25N3O6S, the dihedral angle between the methoxybenzene and indazole rings is 74.96 (5)°. The crystal packing is stabilized by an N—H⋯O hydrogen bond into a two-dimensional network. In addition, C—H⋯π interactions and a π–π contact, with a centroid–centroid distance of 3.5333 (6) Å, are observed. The crystal packing is stabilized by N—H⋯O and C—H⋯O hydrogen bonds.

A mixture of ethyl 3-(6-nitro-2H-indazol-2-yl)propanoate (1.22 mmol) and anhydrous SnCl2 (1.1 g, 6.1 mmol) in 25 mL of absolute ethanol was heated at 60 °C for 3 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-methoxybenzenesulfonyl 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
(eluted with Ethyl acetate: Hexane 1:9).The H atoms bound to C were positioned geometrically and constrained to ride on their parent atoms [C—H distances are 0.93Å for CH groups with Uiso(H) = 1.2 Ueq(C,N), and 0.97 Å for CH3 groups, and the coordinates for the H atom bonded to N were taken from a difference map, and the atom was refined using a riding model.
Various
are widely used as anti-hypertensive (Soledade et al., 2006; Lee & Lee, 2002). In former papers, we reported the crystal structures of N-(7-ethoxy-1H-indazol-4-yl)-4-methylbenzenesulfonamide (Abbassi et al., 2011a) and N-[7-ethoxy-1-(prop-2-en-1-yl)-1H-indazol-4-yl]-4-methylbenzenesulfonamide (Abbassi et al., 2011b). In this communication, the of N-[7-ethoxy-2-(prop-2-en-1-yl)-2H-indazol-6-yl]-4-methylbenzenesulfonamide is reported.In the title compound, C21H25N3O6S, the dihedral angle between the methoxyphenyl and the indazole rings is: 74.96 (5)° (Fig. 1).
Two neighbouring molecules generate a hydrogen-bonded dimer about a center of inversion through a pair of intermolecular N—H···O interactions (Table 1 and Fig. 2).
The crystal packing is stabilized by intermolecular N—H···O and C—H···O H-bonds and C—H···π interactions (Fig. 3). Also, π–π contacts are observed with centroid-centroid distance of 3.5333 (6) Å.

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. |

Various sulfonamides are widely used as anti-hypertensive (Soledade et al., 2006; Lee & Lee, 2002). In former papers, we reported the crystal structures of N-(7-ethoxy-1H-indazol-4-yl)-4-methylbenzenesulfonamide (Abbassi et al., 2011a) and N-[7-ethoxy-1-(prop-2-en-1-yl)-1H-indazol-4-yl]-4-methylbenzenesulfonamide (Abbassi et al., 2011b). In this communication, the crystal structure of N-[7-ethoxy-2-(prop-2-en-1-yl)-2H-indazol-6-yl]-4-methylbenzenesulfonamide is reported.
In the title compound, C21H25N3O6S, the dihedral angle between the methoxyphenyl and the indazole rings is: 74.96 (5)° (Fig. 1).
Two neighbouring molecules generate a hydrogen-bonded dimer about a center of inversion through a pair of intermolecular N—H···O interactions (Table 1 and Fig. 2).
The crystal packing is stabilized by intermolecular N—H···O and C—H···O H-bonds and C—H···π interactions (Fig. 3). Also, π–π contacts are observed with centroid-centroid distance of 3.5333 (6) Å.
