In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1127-59-9 as follows. Related Products of 1127-59-9
Mg(ClO4)2 (0.1 g) was added to a mixture of isatin (2 mmol), and dimedone (4 mmol) in aqueousethanol solution (50percent, v/v, 5 mL), and the resulting mixture was stirred at 80°C 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.
