title: Methyl 2-{1-[(Z)-3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-yl-idene]ethyl-amino}-3-phenyl-propanoate.
abstract: The mol-ecule of the title compound, C(22)H(23)N(3)O(3), exists in the enamine-keto form. A strong intra-molecular N-H⋯O hydrogen bond occurs, generating an S(6) ring. The dihedral angle between the heterocycle and the adjacent phenyl ring is 3.75 (15)°.
