Ethyl 4-anilino-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrrole-2-carboxylate

Abstract

In the title compound, C20H20N2O3, the central 2,5-dihydro-1H-pyrrole ring [r.m.s. deviation = 0.014 (1) Å] is oriented at dihedral angles of 77.81 (6) and 25.33 (6)°, respectively, to the attached phenyl ring and the aniline phenyl ring. An intramolecular N—H...O hydrogen bond occurs. In the crystal, molecules are linked through pairs of N—H...O hydrogen bonds, forming inversion dimers with an R22(10) ring motif. Two weak C—H...π interactions are also observed.
