Adding a certain compound to certain chemical reactions, such as: 56341-37-8, name is 6-Chlorooxindole, 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 56341-37-8, Recommanded Product: 6-Chlorooxindole
To the mixture of 6-chloro-2-oxindole (16.2 g, 92 mmol) (Crescent) and 3-chloro-benzaldehyde (12.9 g, 92 mmol) (Aldrich) in methanol (109 mL) was added pyrrolidine (6.55 g, 92 mmol) (Aldrich) dropwise. The mixture was then heated at 70 C. for 3 h. After cooled to 4 C., the mixture was filtered and resulting precipitate was collected, dried to give a mixture of E/Z-6-chloro-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one as a bright yellow solid (Yield 25.2 g, 95%).
