Diethyl 2,2'-[({2-chloro-5-[(2-eth-oxy-2-oxoeth-yl)(2-methyl-indolin-1-yl)carbamo-yl]phen-yl}sulfon-yl)aza-nedi-yl]di-acetate.

The majority of the title mol-ecule, CHClNOS, is disordered over two closely spaced sets of sites; the site occupancy of the major component = 0.542 (3). The conformation of each component is approximately U-shaped with the chloro-benzene ring forming the base and the indolinyl and sulfamoyl groups the sides; an intra-molecular C-H⋯Cl hydrogen bond possibly contributes to the stabilization of the conformation. In the crystal, a corrugated layer structure parallel to the plane is formed by C-H⋯O and C-H⋯Cl hydrogen bonds together with C-H⋯π(ring) inter-actions.
