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. 169037-23-4, name is 5-(Trifluoromethoxy)indoline-2,3-dione, A new synthetic method of this compound is introduced below., Quality Control of 5-(Trifluoromethoxy)indoline-2,3-dione
General procedure: To the reaction mixture containing isatin (0.5mmol) in water (2mL), indole (0.5mmol), diethanolamine (20mol %) was slowly added at room temperature. After thecompletion of reaction as monitored by TLC, the reaction mixture was washed with brine solution and then extracted with ethyl acetate. The organic layer was dried over anhydrous Na2SO4 and the product was purified by flash chromatography on the silica gel column using a gradient of petroleum ether/ethyl acetate, as eluent to afford pure products 1-41.
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.
