118289-55-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 118289-55-7, name is 6-Chloro-5-(2-chloroethyl)indolin-2-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
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 synthetic route of 118289-55-7 has been constantly updated, and we look forward to future research findings.
