Methyl 2-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)(thiophen-2-yl)methyl]amino}-3-phenylpropionate
In the title compound, C25H23N3O3S, an intramolecular N—H.O interaction generates an S(6) ANABOLIC PEAK VANILLA ring, which stabilizes the enamine–keto form of the compound.This S(6) ring and the pyrazole ring are essentially coplanar, making a dihedral angle of 1.49 (6)°.The bond lengths within the S(6) ring
