In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 60434-13-1 as follows. SDS of cas: 60434-13-1
General procedure: To a flame-dried screw-capped test tube equipped with a magnetic stir bar was added I, 4,7,10,13, 16-hexaoxacyclooctadecane (0.396 g, 1.5 mmol), KF (0.087 g, 1.5 mmol) and 1- methylindoline-2,3-dione 3 (0.50 mmol). Then the screw-capped tube was evacuated and backfilled with argon. The mixture was dissolved in THF (2.0 mL) under argon atmosphere. The resultant reaction mixture was kept stirring at 30 C for 5 min. To the stirring solution was added pyridine 7 (0.75 mmol) and the aryne precursor 2 (0.75 mmol). When TLC control showed the completion of the reaction (typically after 12 h), the reaction stopped and the crude reaction mixture was purified by column chromatography on silica gel to afford the corresponding indolin 2-one derivatives 8 in good yields.
According to the analysis of related databases, 60434-13-1, the application of this compound in the production field has become more and more popular.
