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. 118289-55-7, name is 6-Chloro-5-(2-chloroethyl)indolin-2-one, A new synthetic method of this compound is introduced below., category: indolines-derivatives
General procedure: A mixture of 6-chloro-5-(2-chloroethyl)-1,3-dihydro-2H-indol-2-one 1 (1.00mol), potassium carbonate (1.20mol), secondary amine (2a-h, 1.30mol) in water (10mL) was refluxed until completion (TLC, about 24-48h) and the reaction mass was cooled to RT and then extracted with DCM to get crude 3a-h. Recrystallized using aqueous acetone or aqueous ethanol or methanol (Yield 55-70%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
