The important role of 78593-33-6

With the complex challenges of chemical substances, we look forward to future research findings about 3-Bromocinnoline

Name is 3-Bromocinnoline, as a common heterocyclic compound, it belongs to cinnoline compound, and cas is 78593-33-6, its synthesis route is as follows.,78593-33-6

(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%.

With the complex challenges of chemical substances, we look forward to future research findings about 3-Bromocinnoline
