In the title compound, C19H21N3O3S, the C—SO2—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 methylbenzene ring by 76.87 (7)°.
The vinyl group is disordered over two Combat Boots orientations with site occupancies of 0.622 (10) and 0.378 (10).The S atom HAIR TOOLS has a distorted tetrahedral geometry [maximum deviation: O—S—O = 119.
18 (11)°].An intramolecular C—H.O hydrogen bond occurs.In the crystal, two molecules are linked about a center of inversion by pairs of N—H.
O hydrogen bonds, generating a dimer.C—H.π interactions are also observed.
