92525-10-5, name is 3-Iodo-1-methyl-1H-pyrazole, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of 3-Iodo-1-methyl-1H-pyrazole
A) A solution of 3-iodo-1-methyl-1H-pyrazole (200 mg), 3,3-dimethylpyrrolidin-2-one (109 mg), copper(I) iodide (73 mg), N1,N2-dimethylethane-1,2-diamine (0.083 mL) and tripotassium phosphate (408 mg) in cyclopentyl methyl ether (4 mL) was stirred overnight at 120 C. To the reaction mixture was added saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (170 mg). MS (ESI+): [M+H]+: 194.1
The synthetic route of 92525-10-5 has been constantly updated, and we look forward to future research findings.
