N-(2-allyl-4-ethoxy-2H-indazol-5-yl)-4-methylbenzenesulfonamide

Abstract

The indazole ring system of the title compound, C19H 21N3O3S, is almost planar (r.m.s. deviation = 0.0192Å) and forms dihedral angles of 77.99(15) and 83.9(3)° with the benzene ring and allyl group, respectively. In the crystal, centrosymmetrically related molecules are connected by pairs of N - H⋯O hydrogen bonds into dimers, which are further linked by C - H⋯O hydrogen bonds, forming columns parallel to the b axis. © 2014 CrossMark.
