In the title compound, C18H16ClNO2S, the indole ring system forms a dihedral angle of 75.07 (8)° with the phenyl ring. The molecular structure is stabilized by a weak intramolecular C-HO hydrogen bond. In the crystal, molecules are linked by weak C-HO hydrogen bonds, forming a chain along [10-1]. C-H interactions are also observed, leading to a three-dimensional network.
