Adding a certain compound to certain chemical reactions, such as: 99365-40-9, name is 6-Bromoindolin-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 99365-40-9, Recommanded Product: 6-Bromoindolin-2-one
General procedure: To the phenstatin-3-aldehyde/isocombretastatin-3-aldehyde(16a-b) (0.303 mmol/0.304 mmol) prepared in the above stepwas added corresponding substituted oxindoles (17a-h)(0.303 mmol) and catalytic amount of piperidine (1.0 ml) in ethanol.Heated the reaction mixture to reflux for 4 h at 85 C. The solidcompounds obtained in the reaction vessel were filtered and washed with ethanol for 4-5 times. After complete air drying thefinal compounds phenstatin/isocombretastatin-oxindole analogs(5a-h and 6a-h) were obtained as pure solids (yield 71-90%).
