These common heterocyclic compound, 7699-18-5, name is 5-Methoxyindolin-2-one, its 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. Quality Control of 5-Methoxyindolin-2-one
General procedure: To a Schlenk tube were added indolin-2-one 1 (0.3 mmol), t-BuOOH (0.6 mmol), and DCE (2 mL). Then the tube was stirred at 85 oC under air for the indicated time until complete consumption of starting material monitored by TLC analysis. After the reaction was finished, the reaction mixture was washed with brine. The aqueous phase was re-extracted with ethyl acetate (3¡Á10 mL). The combined organic extracts were dried over Na2SO4, removal of the solvent under vacuum afforded the crude product, which was purified further by column chromatography using hexane-ethyl acetate (10:1).
The synthetic route of 5-Methoxyindolin-2-one has been constantly updated, and we look forward to future research findings.
