Methyl 2-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)(4-nitrophenyl)methyl]amino}-3-phenylpropanoate

Abstract

The molecule of the title compound, C27H24N4O5, exists in the keto–enamine tautomeric form, stabilized by an intramolecular N—H...O hydrogen bond. An intramolecular C—H...·O hydrogen bond also occurs. In the crystal, C—H...O hydrogen bonds link the molecules into chains.
