N-(3-Chloro-4-eth­oxy-1-methyl-1H-indazol-5-yl)-4-meth­oxy­benzene­sulfonamide

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-eth­oxy group, respectively. In the crystal, mol­ecules are connected by pairs of N—H...O hydrogen bonds into inversion dimers, which are further linked by π–π inter­actions between the diazole rings [inter­centroid distance = 3.4946 (11) Å], forming chains parallel to [101].
