Ethyl 6-chloro-2-oxo-4-phenyl-1,2-dihydroquinoline-3-carboxylate

Abstract

In the title compound, C18H14ClNO3, the dihydro-quinolin-2-one ring system is almost planar (r.m.s. deviation = 0.033 Å). The carboxyl-ate plane and the phenyl group are twisted away from the dihydro-quinolin-2-one ring system by 50.3 (1) and 64.9 (1)°, respectively. In the crystal structure, inversion-related mol-ecules form R 2 2(8) dimers via pairs of N - H⋯O hydrogen bonds.
