Downstream synthetic route of 78593-33-6

The synthetic route of 78593-33-6 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78593-33-6,3-Bromocinnoline,as a common compound, the synthetic route is as follows.

(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%

78593-33-6 3-Bromocinnoline 12678051, acinnoline compound, is more and more widely used in various.

78593-33-6, 3-Bromocinnoline is a cinnoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

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%.
