Abstract: In the title compound, C₁₈H₁₄ClNO₃, the dihydroquinolin-2-one ring system is almost planar (r.m.s. deviation = 0.033 Å). The carboxylate plane and the phenyl group are twisted away from the dihydroquinolin-2-one ring system by 50.3 (1) and 64.9 (1)°, respectively. In the crystal structure, inversion-related molecules form R₂²(8) dimers via pairs of N-HO hydrogen bonds.
