Methyl 2-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)(thiophen-2-yl)methyl]amino}-3-phenylpropionate
In the Lunchbox title compound, C25H23N3O3S, an intramolecular N—H.O interaction generates an S(6) 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 of keychain t
