In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 4522-35-4 as follows. SDS of cas: 4522-35-4<\/a><\/p>\n

To 3-iodo-lH-pyrazole (763 mg, 3.93 mmol) in DMSO (15 mL) at 0 C, was added sodium hydride (60% in mineral oil, 189 mg, 4.72 mmol). The reaction was warmed to 25 C and stirred for 60 min before 4-fluoro-2-methoxypyridine (500 mg, 3.93 mmol) was added. The reaction mixture was stirred at 90 C for 4.5 h before quenching by the addition of water. The reaction mixture was extracted with EtOAc. The combined organic extracts were dried over MgS04 and concentrated in vacuo. The crude mixture was purified by flash chromatography (ISCO Combiflash, 0-30% EtOAc in hexanes) to afford 4-(3- iodo-lH-pyrazol-l-yl)-2-methoxypyridine, as a white solid. LCMS calc. = 301.97; found = 302.02 (M+H)+.<\/p>\n
