Crystal structure of N-(1-allyl-3-chloro-4-ethoxy-1H-indazol-5-yl)-4-methoxybenzenesulfonamide

Abstract

In the title compound, C19H20ClN3O4S, the benzene ring is inclined to the indazole ring system (r.m.s. deviation = 0.014Å) by 65.07(8)°. The allyl and ethoxy groups are almost normal to the indazole ring, as indicated by the respective torsion angles [N-N-C-C = 111.6(2) and C-C-O-C = -88.1(2)°]. In the crystal, molecules are connected by N-H⋯N hydrogen bonds, forming helical chains propagating along [010]. The chains are linked by C-H⋯O hydrogen bonds, forming a three-dimensional network.
