Methyl N-[(4-chlorophenyl)(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)methyl]glycinate

The title compound, C20H18ClN3O3, is in an enamine-keto form, stabilized by two strong intramolecular N-H center dot center dot center dot O hydrogen bonds. The pyrazole ring is oriented at dihedral angles of 4.13 (3) and 85.60 (3)degrees with respect to the aromatic rings. The dihedral angle between the aromatic rings is 81.79 (3)degrees. In the crystal structure, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into double chains, which are further linked by weak C-H center dot center dot center dot pi interactions, forming a two-dimensional network.
