Application of 3484-35-3,Some common heterocyclic compound, 3484-35-3, name is 5-Methylindolin-2-one, molecular formula is C9H9NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Equimolar quantity of 5-substituted-1H-indolin-2-ones and 2-(4-formylphenoxy)-N-substituted-phenyl-acetamide was taken into round bottom flask containing 50 mL of methanol, followed by 2-3 drops of piperidine. The reaction mixture was refluxed for 1-4 h or till the end of reaction as confirmed by TLC. Then, it was cooled to room temperature and, the solution was filtered. The obtained residue was recrystallized by using dimethylformamide and ethanol.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Methylindolin-2-one, its application will become more common.
