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.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
