Electric Literature of 39603-24-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39603-24-2, name is 5,7-Dimethylindoline-2,3-dione, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: The mixture of isatin 1 (29.4 mg, 0.2 mmol), antipyrine 2a (84.7 mg, 0.45 mmol) in 1mL H2O were stirred at 120 . Once the reaction completed (indicated by colorchange from red to white), the mixture was then cooled down to the room temperature.The insoluable solid mixture was filtered, washed by water and dried under vacuum to afford the desired product 4a in high pure form.
The chemical industry reduces the impact on the environment during synthesis 5,7-Dimethylindoline-2,3-dione. I believe this compound will play a more active role in future production and life.
