YieldReaction ConditionsOperation in experiment
83% With palladium diacetate; silver carbonate; In acetonitrile; at 90℃; for 12h;Sealed tube; General procedure: A mixture of 5-pyrazolones 1 (0.3 mmol), aryl halids (0.6 mmol), Pd(OAc)2 (0.03 mmol) and Ag2CO3 (0.6 mmol) in 2 mL MeCN was placed in a sealed tube. The tube was heated at 90 C for 12 h using an oil bath. After the reaction was completed (as monitored by TLC), the mixture was cooled to room temperature, and then concentrated under reduced pressure to afford a crude product Purification by column chromatography on silica gel (EtOAc) to yield 4-aryl-5-pyrazolones 3.

YieldReaction ConditionsOperation in experiment
General procedure: A reaction mixture containing aryl hydrazine (2 mmol), ethyl acetoacetate (2 mmol), molecular sieves (4 A) and toluene (4 mL) was stirred in the dark in a sealed tube maintained at 120 C in an oil bath. After 17 h, the reaction mixture was cooled to room temperature. To this mixture, acetonitrile (2 mL) and iodomethane (6 mmol) were added successively and stirred in the dark in the sealed tube maintained at 120 C for additional 17 h, After the reaction was completed, the mixture was cooled to room temperature. The solvent was then evaporated in vacuo. The resulting residue was purified by flash column chromatography (ethyl acetate) to yield 1b-l.

YieldReaction ConditionsOperation in experiment
86% With 1H-imidazole; In water; at 80℃; for 48h; Mix 0.4 mmol of eosin, 0.2 mmol of 2-p-methylphenyl-1,5-dimethyl-1H-pyrazole-3-(2H)-one, 0.04 mmol of imidazole and 1 mL of water in an oil bath at 80 C The reaction was stirred under heating for 48 h.The resulting reaction system is then cooled to room temperature, extracted with dichloromethane, and the organic phase is collected. The obtained organic phase is dried over anhydrous sodium sulfate, concentrated, and separated by column chromatography (mobile phase: petroleum ether / ethyl acetate volume ratio) In the order of 4/1, 3/1, 2/1 and 1/1), the title compound I-23 (light yellow solid, yield 86%, purity 99.5%) was obtained.
86% With 1H-imidazole; In water; at 80℃; for 48h;Green chemistry; General procedure: The mixture of isatin 1 (58.9 mg, 0.4 mmol), antipyrine 2 (37.6 mg, 0.2 mmol) andimidazole (20 mol %, 0.04 mmol) in 1 mL H2O were stirred at 80 . Once thereaction completed, the solid mixture was filtered, washed by water and dried undervacuum to afford the analytically pure products 3. In some cases, the desired pureproducts were obtained by silica gel chromatography using ethyl acetate as eluent.

YieldReaction ConditionsOperation in experiment
45% In acetonitrile; at 120℃; for 17h;Darkness; Sealed tube; General procedure: A mixture containing 4-fluorophenylhydrazine hydrochloride or 4-bromophenylhydrazinehydrochloride (4.47 mmol), ethyl acetoacetate (565 uL, 4.47 mmol) and 2.0mL of acetic acid was reflux for 8 h. The solution was then cooled to ambienttemperature and concentrated in vacuo. The crude product was purified by silica gelflash chromatography (PE/EA = 3/1, v/v) to afford 1-aryl-3-methyl-1H-pyrazol-5(4H)-one. Then 2.0 mmol 1-aryl-3-methyl-1H-pyrazol-5(4H)-one (R = 4-F, 4-Cl,4-Br, 4-CH3, 4-CH3O) was reacted with iodomethane (6 mmol) and acetonitrile (4 mL)in the dark in a sealed tube maintained at 120 in an oil bath. After 17 h, themixture was cooled to room temperature. The solvent was then evaporated in vacuo,and the resulted residue was purified by flash column chromatography (ethyl acetate)to yield 2t-2x.
