Adding a certain compound to certain chemical reactions, such as: 6341-92-0, name is 6-Chloroisatin, 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 6341-92-0, Computed Properties of C8H4ClNO2
General procedure: In the presence of K2CO3 (1mol) and tetrabutylammonium bromide (1mol), isatin or substituted isatin 6a-i (0.5mol) was reacted with BnBr or CH3I (1mol) in DMF (6L) and the reaction mixture was stirred 12h at room temperature. Intermediates 6j-p were obtained by filtration and purified by recrystallization from acetic acid with high yield (72.7%-85.1%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 6-Chloroisatin, and friends who are interested can also refer to it.
