In the 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 the molecule lie between classical single- and double-bond lengths, indicating extensive conjugation. The structure exhibits a thienyl-ring flip disorder, with occupancy factors in the ratio 64.7 (3):35.3 (3).

The title compound was synthesized by refluxing the mixture of 1-phenyl-3-methyl-4-(2-thenoyl)pyrazolone-5 (HPMTP) (10m mol) and phenylalanine methyl ester(10m mol) in ethanol (100 ml) over a steam bath for about 7 h, then the solution was cooled down to room temperature. After five days, pale yellow blocks were obtained and dried in the air. The product was recrystallized from ethanol which afforded pale yellow crystals suitable for X-ray analysis.
The disorder model of thiazole ring was refined using the tools available in SHELXL97 (Sheldrick, 2008): DFIX for restraining distances, FLAT for constraining the thienyl rings to be planar, SIMU for restraining the same Uij and ISOR for restraining atoms to be approximately isotropic.
All H atoms were geometrically positioned and treated as riding on their parent atoms, with C—H = 0.93 Å for the aromatic, 0.96 Å for the methyl and N—H= 0.88 Å with U\ĩso\~(H)= 1.2 U\~eq\~C(aromatic, N) or, 1.5U\~eq\~C(methyl).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Pyrazole derivatives have drawn attentionfrom agricultural chemists for their high biological activity and low toxicity. They are widely used as pesticide, miticide and weed killers, and with the positional changes of the substituent group of pyrazole ring, more and more new pyrazole agricultural chemicals are synthesized and commercialized (Tan et al.,2009), so pyrazole derivatives have become one of the focal points to the creation of new agricultural chemicals. Amino acid esters also possess good antibacterial and biological activity (Xiong et al.,1993).
In the molecule of the title compound (Fig. 1), there is an intramolecular N3—H1···O1 interaction that generates a S(6) ring, and stabilizes the enamine–keto form of the compound. The dihedral angle between this S(6) ring and the pyrazole ring is 1.49 (6)°, indicating that they are essentially coplanar, as seen in Methyl 2-{[(1Z)-(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4- ylidene)(methyl)methyl]amino}-3-phenylpropanoate(1.50 (15)°; Zhu et al., 2010). The bond lengths within this part of the molecular lie between classical single-and double-bond lengths, indicating extensive conjugation. The S(6) ring makes dihedral angles of 54.29 (6)°,82.21 (22)° and 28.53 (6)° with the benzene ring of phenylalanine methyl ester, the thiazole ring and benzene ring bonded to pyrazole ring, respectively.
Atoms N3, C16, C24 and O2 are not coplanar, the torsion angle is 37.17 (22)°, similar to some other 4-acylpyrazolone Schiff Bases (Zhang et al., 2010). The bond lengths in this part of the molecule indicate that only C24—O2 is a classical double bond, other bonds are classical single bonds.
The structure exhibits a thienyl-ring flip disorder with the occupancy factors in the ratio 67/33.
