Adding a certain compound to certain chemical reactions, such as: 1186647-69-7, 4-Chloro-3-iodo-1H-pyrazolo[4,3-c]pyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, category: pyridine-derivatives, blongs to pyridine-derivatives compound. category: pyridine-derivatives
A solution of 4-chloro-3-iodo-1H-pyrazolo[4,3-c]pyridine (103) (50 mg, 0.179 mmol) in DMF (1 mL) was cooled to 0 C, NaH (8.6 mg, 1.2 eq, 0.215 mmol) was added slowly and then 2-bromopropane was added dropwise. The solution was stirred overnight at room temperature. The mixture was concentrated in vacuo. The crude product was then purified by column chromatography using a gradient of CH2Cl2 in hexanes to afford 4-chloro-3-iodo-1-isopropyl-1H-pyrazolo[4,3-c]pyridine (301) (30 mg, 53% yield) as a white solid.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1186647-69-7, 4-Chloro-3-iodo-1H-pyrazolo[4,3-c]pyridine, and friends who are interested can also refer to it.
