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) ring, which stabilizes the enamine–keto form ardell soft touch 150 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
