Adding a certain compound to certain chemical reactions, such as: 20870-90-0, name is 5-Bromo-1-methyl-2-oxoindoline, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 20870-90-0, Quality Control of 5-Bromo-1-methyl-2-oxoindoline
General procedure: To a Schlenk tube were added oxindole 1 (0.3 mmol), t-BuONO (0.6 mmol), andTHF (2 mL). Then the tube was stirred at 50 C under 1 atm of O2 for the indicatedtime 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. The combined organic extractswere dried over Na2SO4, removal of the solvent under vacuum afforded the crudeproduct, which was purified further by column chromatography using hexane-ethylacetate.
