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. 317-20-4, name is 7-Fluoroisatin, A new synthetic method of this compound is introduced below., COA of Formula: C8H4FNO2
General procedure: A mixture of isatins 1 (1 mmol), substituted 1H-pyrazol-5-amine 2 (1 mmol), 6-aminopyrimidine-2,4(1H,3H)-dione 3 or 6-amino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione 5 (1 mmol), H2O(6 mL), and HOAc (2 mL) was placed in a 25-mL flask andstirred at 90 C (monitored by thin layer chromatography (TLC)) for about 7 h. Afterreaction completion, the mixture was cooled to room temperature and the precipitateobtained by filtration. Compounds 4 or 6 were further purified by recrystallizationfrom DMF.
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.
