Ethyl 4-(4-chloroanilino)-1-(4-chlorophenyl)-2-methyl-5-oxo-2,5-dihydro-1H-pyrrole-2-carboxylate
Abstract
In the title compound, C20H18Cl2N2O3, the dihedral angles between the central 2,5-dihydro-1H-pyrrole ring and the phenyl rings are 74.87 (9) and 29.09 (9)°. Intramolecular N—H...O and C—H...O hydrogen bonds occur. In the crystal, pairs of N—H...O hydrogen bonds link adjacent molecules into inversion dimers and form an R12(6)R22(10)R12(6) ring motif through C—H...O hydrogen bonds.
