Adding a certain compound to certain chemical reactions, such as: 78593-33-6,3-Bromocinnoline, 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 78593-33-6,78593-33-6

Starting material 1-A (11.8 g, 40 mmol), starting material 1-B (16.7 g, 80 mmol), CuI (3.8 g, 20 mmol), potassium carbonate (11.1 g, 80 mmol), and 1-methyl-1H-imidazole (3.3 g, 40 mmol) were added to 250 ml of toluene, and then, the mixture was refluxed while stirring under a nitrogen atmosphere for 7 days. Then, the reaction mixture was cooled to room temperature, 300 ml of water was added to isolate the organic layer, and the water layer was extracted twice with 250 ml of dichloromethane. The extracted organic layer was stirred with MgSO4 to remove water therefrom, and the organic layer was filtered and evaporated under reduced pressure. The resulting solid was subjected to column chromatography using, as an eluent, dichloromethane and normal hexane to obtain 5.6 g of Intermediate 1-C at the yield of 33%. MS (MALDI-TOF) m/z: 424 [M]+

According to the analysis of related databases, 78593-33-6, the application of this compound in the production field has become more and more popular.

78593-33-6,Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials.78593-33-6,A new synthetic method of this compound is introduced below.

(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50 ml of dimethylsulphoxide was stirred and heated at 120 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained. Yield: 10.2%.
