In the title compound, C15H10ClN3O2, the benzene ring is slightly twisted out of the plane of the 2,3-dihydro-1H-indole ring system (r.m.s. deviation = 0.007 Å), forming a dihedral angle of 7.4 (3)°. An intramolecular N-HO hydrogen bond forms a six-membered ring. In the crystal, molecules are linked via N-HO and C-HO hydrogen bonds, forming layers alternately perpendicular to  and [0-11].
