Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 71759-89-2, name is 5-Iodo-1H-imidazole, A new synthetic method of this compound is introduced below., Recommanded Product: 71759-89-2
Intermediate 4.1 : (5-chloro-2-nitro-phenyl)-(lH-imidazol-4-yl) methanol To a solution of 4-iodo-lH-imidazole (2 g, 10.3 mmol) in THF (20 mL) was added dropwise isopropylmagnesiumchloride (2 M in THF, 12 mL, 23.7 mmol) at room temperature. The reaction solution was stirred at rt for 2 h. To this solution was added 5-chloro-2-nitro-benzaldehyde (2.9 g, 15.5 mmol) in 10 mL THF. The solution was stirred at room temperature for 2 h. The reaction was quenched with aqueous NH4CI solution. The mixture was extracted twice with EA. The combined organic phases were dried and concentrated in vacuo. The residue was purified silica gel chromatography column (PE/EA, 3/1 to 1/1) to give the title compound as a brown solid
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
