Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 64483-69-8, name is 5-Acetylindolin-2-one, A new synthetic method of this compound is introduced below., SDS of cas: 64483-69-8
EXAMPLE II 1,5-diacetyl-2-indolinone 48.9 g (0.279 mol) 5-acetyl-2-indolinone are stirred for 2 h in 400 ml acetic anhydride in an oil bath at 140 C. The starting material dissolves. Then the reaction mixture is left to cool, evaporated down, the precipitate is removed by suction filtering, washed with diethylether and the product is dried. Yield: 56.0 g (92.4% of theory) Rf=0.41 (silica gel, methylene chloride/methanol 50:1) C12H11NO3 (MW=217.223) Mass spectrum: m/z=216 (M-H)-
The synthetic route of 64483-69-8 has been constantly updated, and we look forward to future research findings.
