324-03-8, A common compound: 324-03-8, name is 6-Fluoroindoline-2,3-dione, belongs to indolines-derivatives compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
Mg(ClO4)2 (0.1 g) was added to a mixture of isatin (2 mmol), and dimedone (4 mmol) in aqueousethanol solution (50%, v/v, 5 mL), and the resulting mixture was stirred at 80C for 10-12 h. Upon completion of the reaction (TLC, Ethyl acetate/Petroleum ether = 1:4), the mixture was allowedto cool to room temperature. The resulting solid was filtered and washed successively with water(2 30 mL) and cold aqueous ethanol (2 1 mL) to afford a crude product, which was recrystallizedfrom EtOH to afford the pure product 3. Some insolubility could be observed in the refluxing ethanolduring the recrystallization process, which should be filtered when hot.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 6-Fluoroindoline-2,3-dione, other downstream synthetic routes, hurry up and to see.
