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 64483-69-8 as follows. category: indolines-derivatives
General procedure: Indolinone 1 (1000 mg, 52.3 mmol) was suspended in acetic anhydride (10 mL) and refluxed at 130 C for 8 h. The reaction mixture was allowed to cool to 50 C and (triethoxymethyl)benzene(2930 mg, 131 mmol) was added. The resulting reaction mixture was stirred at 120 C for 6 h. Then, volatiles were removed in vacuo and petroleum ether was added to the obtained residue. After triturating for 15 min, the separated solids were filtered and washed with petroleum ether and then dried under vacuum to afford974 mg (51%) of title compound.
According to the analysis of related databases, 64483-69-8, the application of this compound in the production field has become more and more popular.
