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. 3469-69-0, name is 4-Iodopyrazole, A new synthetic method of this compound is introduced below., name: 4-Iodopyrazole
4-iodopyrazole (20 g) and ethanol (100 ml) were added and stirred uniformly. KOH (11.6 g) and KI (0.9 g) were added and the methyl chloride gas was introduced into the liquid surface, Control temperature 30_45 C, GC tracking reaction end, add water 100g, dichloromethane extraction (40gX3), Concentrated to no flow liquid, with n-heptane 6ml beating, suction filter white solid, dry, weighing 17.2g, GC purity 98%, yield 80%;
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.
