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. 51516-70-2, name is 5-Amino-1-(4-fluorophenyl)-1H-pyrazole-4-carbonitrile, A new synthetic method of this compound is introduced below., Recommanded Product: 5-Amino-1-(4-fluorophenyl)-1H-pyrazole-4-carbonitrile

General procedure: Intermediate 4 (0.001mol) and 5 (0.001mol) were dissolved in pyridine, phosphorus oxychloride is slowly added dropwise under ice bath conditions, then at 40-60C reacted for 5-8h. Finally, the mixture was poured into 30mL saturated Na2CO3 solution and stirred well. After the mixture was acidified, the saturated CuSO4 solution was used to remove pyridine, which greatly improved the purity and yield of the product. The data for compounds 8I-8VI are provided in the supporting information.

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.
