The important role of 119-39-1

With the complex challenges of chemical substances, we look forward to future research findings about Phthalazin-1(2H)-one

Name is Phthalazin-1(2H)-one, as a common heterocyclic compound, it belongs to phthalazine compound, and cas is 119-39-1, its synthesis route is as follows.,119-39-1

Stage A 2-{2-[(Tetrahydro-2-pyranyl)oxy]ethyl}-1-oxophthalazine A solution of 41.5 g of potassium hydroxide in 53 ml of water is added at room temperature to a solution of 61 g of 1-oxophthalazine in 430 ml of dimethyl sulfoxide. After 30 minutes, 130 g of tetrahydro-2-pyranyl 2-bromoethyl ether are added to the suspension obtained. The mixture is left stirring for 30 hours at room temperature and then concentrated, the residue is taken up in 400 ml of water and the product is extracted with dichloromethane. The organic phase is concentrated. Yield: 80% Proton nuclear magnetic resonance spectrum (400 MHz, solvent CDCl3): 1.3 to 2 ppm,m,6H; 3.3 to 4.8 ppm,m+m, 1H+6H; 7.6 to 7.9 ppm,m,3H; 8.15 ppm,s,1H; 8.4 ppm,m,1H

With the complex challenges of chemical substances, we look forward to future research findings about Phthalazin-1(2H)-one
