Source of material
Ethyl-1,5-dimethyl-1H-pyrazole-3-carboxylate (2.02 g; 12.01 mmol) was slowly added to a solution of metallic sodium (0.35 g; 15.21 mmol) in 50 mL of anhydrous toluene. Then, acetophenone (1.44 g; 12.01 mmol) in 10 mL of toluene was added at 0 °C. The resulting mixture was stirred at room temperature for 7 days. The precipitate formed was filtered, washed with toluene, dissolved in water and neutralized with acetic acid. The product extracted with CH2Cl2 was concentrated in vacuo and precipitated in hexane. Crystals of the title compound were obtained from hot ethanol by slow evaporation. Yield: 32%; M.p. 108–110 °C.

Experimental details
All hydrogen atoms were inserted at calculated positions and refined using a riding model. The Uiso values of the hydrogen atoms of methyl groups were set to 1.5Ueq(C) and the Uiso values of all other hydrogen atoms were set to 1.2Ueq of their parent atoms.
Discussion
Many heterocycles branched β-keto-enol are useful synthetic intermediates in a wide variety of applications including anti-tumor [1, 2, 3], anti-inflammatory [4] and anti-HIV [5, 6] activities. Recently, we have reported some new heterocyclic keto-enol compounds that have shown remarkable biological activities [7] and efficient coordination properties [8, 9]. Herein, we report a β-keto-enol compound: (Z)-1-(1,5-dimethyl-1H-pyrazol-3-yl)-3-hydroxy-3-phenylprop-2-en-1-one, prepared in acceptable yield. The crystal structure shows the formation of an intramolecular (O1—H—O2) interaction balancing the intra-electrostatic forces. The two oxygen atoms O1, O2 are separated by a distance of 2.480(3) Å. Furthermore, the N1—N2 distance (1.349(3) Å) is in good agreement with the lengths of bonds reported for analogous compounds [10]. The N1, N2, C4, C5, and C6 atoms are in the same plane. The r.m.s. deviation is 0.002 Å. The torsion angle O2—C3—C4—N2 of -174.1(3) indicates that the pyrazole ring undergoes slight inclination with respect to the binding C3—C4. Also the phenyl atoms are in the same plane (0.005 Å), while the torsion angle O1—C1—C9—C14 of -167.6(3)° indicates that the plane of phenyl ring undergoes a inclination relative to plane of the rest of the molecule.
