39603-24-2, name is 5,7-Dimethylindoline-2,3-dione, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 5,7-Dimethylindoline-2,3-dione
General procedure: A mixture of aromatic diamine derivatives (2 mmol) and a 1,2-dicarbonyl compound (2 mmol) in ionic liquid (2 mL) was stirred atroom temperature for the appropriate time. The progress of the reaction was monitored by TLC (n-Hexane: EtOAc, 7:3), after completion of the reaction, the reaction mixture was diluted with water and extracted using diethyl ether (30 ml). The combined organic layer was dried over anhydrous sodium sulphate and evaporated under reduced pressure to afford the corresponding product. The residual ionic liquid was dried under vacuum and reused. The same procedure was repeated for the reaction of aromatic anilines with isatin and acenaphthoquinone and phenaacylbromide. All the products obtained were characetrised by IR,1HNMR, 13CNMR and Mass studies.
The synthetic route of 39603-24-2 has been constantly updated, and we look forward to future research findings.
