title: N-[7-Eth-oxy-1-(prop-2-en-1-yl)-1H-indazol-4-yl]-4-methyl-benzene-sulfonamide.
abstract: In the title compound, C(19)H(21)N(3)O(3)S, the C-SO(2)-NH-C torsion angle is 103.72 (11)°. The almost planar indazole ring [r.m.s. deviation = 0.0202 (14) Å] is twisted away from the methyl-benzene ring by 76.87 (7)°. The vinyl group is disordered over two orientations with site occupancies of 0.622 (10) and 0.378 (10). The S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 119.18 (11)°]. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, two mol-ecules are linked about a center of inversion by pairs of N-H⋯O hydrogen bonds, generating a dimer. C-H⋯π inter-actions are also observed.
