A mixture of 3-(4-(diethylamino)phenyl)-1-(pyridin-2-yl)prop-2-en-1-one (2.8 g, 10 mmol), phenylhydrazine (1.5 ml) and acetic acid (10 ml) was refluxed for 4 h, cooled and Na2CO3 was added to modify the pH under vigorously stirring. to pH = 7. The mixture was washed with dichloromethane and the solution was evaporated and the crude product was obtained and purified by flash column chromatography (silica, 10:1 petroleum ether: ethyl acetate) to obtain light yellow crystals. Yiels: 40%. 1H NMR (400 MHz, DMSO-d6) 1.03 (t, 6H), 3.11 (q, 1H), 3.25 (q, 4H), 3.86 (q, 1H) 5.37 (q, 1H), 6.57 (d, 2H), 6.74 (t, 1H), 7.06(q, 4H), 7,17(t, 2H), 7.30 (t, 1H), 7.82 (t, 1H) 8.09 (d, 1H), 8.54 (d, 1H).
All hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 Å and Uiso(H) = 1.2 Ueq. The ethyl groups of the N,N-diethylamino group are disordered over two positions. Restraints were imposed on C-C and C-N distances and displacement parameters in these groups.

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. |

The derivatives of the title compound are often used in medicinal chemistry and biochemistry (Guo et al. 2010; Liu et al. 2010). Herewith , in this study, we report the crystal structure of the title compound.
The pyrazoline ring is nearly coplanar to the benzene ring and the pyridine ring, with the dihedral angles of 4.53 (1)° and 6.26 (1)°, respectively (Fig.1). The anilinegroup is almost perpendicular to the pyrazoline ring, with a dihedral angle of 79.96 (1)°. The ethyl groups of the N,N-diethylaniline unit are disordered.
