Adding a certain compound to certain chemical reactions, such as: 7699-18-5, name is 5-Methoxyindolin-2-one, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7699-18-5, Product Details of 7699-18-5
General procedure: A mixture of 2a-j (1.50 mmol) and 5 (1.50 mmol) in ethanol (10 mL) was treated with a catalytic amount of piperidine. The reaction mixture was stirred under reflux until complete consumption of the substituted indolin-2-ones was observed by TLC. After cooling, the precipitate was filtered, recrystallised from absolute ethanol and dried in air to furnish pure (E)-3-(benzothiazol-2-ylmethylene)indolin-2-ones 6a-j.
