39806-90-1<\/a>, These common heterocyclic compound, 39806-90-1, name is 4-Iodo-1-methyl-1H-pyrazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

General procedure: Step 2: 1-[(1-methyl)-4-pyrazolyl]ethanone 1-methyl-4-iodopyrazole (10 g), vinyl-n-butyl ether (24 g), palladium acetate (396 mg), 1,3-bi(diphenyl phosphine)propane (988 mg), sodium carbonate (12.7 g) and n-butylalcohol (100 mL) were added in a round bottomed flask (250 mL). The mixture was refluxed under an argon atmosphere for 4 h, cooled to room temperature, filtrated and treated under reduced pressure to remove solvent thereof. The residue was purified by column chromatography (dichloromethane: methanol=50: 1) to get 1-[(1-methyl)-4-pyrazolyl]ethanone (2.4 g) as yellowish solid. 1H-NMR (300Hz, CDCl3) delta: 7.88 (s, 1H), 7.85 (s, 1H), 3.93 (s, 3H), 2,42 (s, 3H).<\/p>\n
