YieldReaction ConditionsOperation in experiment
Production Example 186 3-(2-Fluoro-4-methylphenyl)-1H-pyrazole 54 ML solution of 5.0 g 1-bromo-2-fluoro-4-methylbenzene, 10 g tributyl(1-ethoxyvinyl)tin and 1.53 g tetrakis(triphenylphosphine) palladium in toluene was heated at 120C for 2 hours.. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate, 10% aqueous potassium fluoride solution was added thereto and stirred for 30 minutes, and formed insolubles were filtered off through Celite. The organic layerwaswashedwith water, thenhydrolyzed by vigorously stirring it together with 5 N aqueous hydrochloric acid, and the organic layer was further washed with water and brine.. The solution was dried over anhydrous sodium sulfate, then the solvent was removed, and the resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give 4.61 g of 2'-fluoro-4'-methylacetophenone (yellow oil) as a crude product.. From 4.61 g crude 2'-fluoro-4'-methylacetophenone, 4.1 g of the title compound (yellow oil) was obtained by the same method as in Production Example 3.1H-NMR (CDCl3) delta: 2.32(d, J=1.2Hz, 3H), 6.56(d, J=2.4Hz, 1H), 7.04(dd, J=8.8, 8.8Hz, 1H), 7.39-7.45 (m, 1H), 7.50-7.57 (m, 1H), 7.61 (d, J=2.4Hz, 1H)
