YieldReaction ConditionsOperation in experiment
In ethylene glycol; EXAMPLE 2 Preparation of 4-(4-phenyl-3-pyrazolyl)-4H-1,2,4-triazole, Method B A slurry of 3-amino-4-phenylpyrazole (1.6 g, 0.01 mole) and sym-<strong>[628-36-4]diformylhydrazine</strong> (2.2 g, 0.025 mole) in ethylene glycol (10 ml) is prepared and heated slowly to 80° C, at which point a clear solution is obtained. Heating is continued to 150° C and the solution held at 150° C to 180° C for 3 hours. The mixture is then cooled to 60° C and filtered to give 1.3 g of product. A second fraction of 0.3 g is obtained by diluting the filtrate with water.

YieldReaction ConditionsOperation in experiment
89% In ethanol; for 6h;Reflux; General procedure: To a warm solution of 3(5)-amino-4-phenyl-1H-pyrazole 1 (1.0 g, 6.2 mmol) in ethanol (20 ml) was added 1,1,1,5,5,5-hexafluoropentan-2,4-dione 3a (1.3 g, 6.2 mmol) and the mixture was refluxed for 6 h. The reaction was monitored by TLC carried out on pre-coated silica gel glass plates. The pale yellow solid obtained on cooling was recrystallised from ethanol. All other compounds, 4b?l, were synthesized according to procedure mentioned for 4a using 1?2 with fluorinated-b-diketones 3a?f.
