title: N-(3-Chloro-4-eth-oxy-1-methyl-1H-indazol-5-yl)-4-meth-oxy-benzene-sulfonamide.
abstract: The indazole ring system of the title compound, C17H18ClN3O4S, is almost planar (r.m.s. deviation = 0.0113 Å) and forms dihedral angles of 32.22 (8) and 57.5 (3)° with the benzene ring and the mean plane through the 4-eth-oxy group, respectively. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into inversion dimers, which are further linked by π-π inter-actions between the diazole rings [inter-centroid distance = 3.4946 (11) Å], forming chains parallel to [101].
