119-39-1, Phthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To the solution of sodium methoxide (0,0151 mol of Na in dry methanol 40 ml) was added 2/f-phthalazin-l-on (0,01368 mol). The mixture was stirred and heated at reflux for 30 minutes. Then solvent was evaporated and the obtained sodium salt of phthalazinone was dried in vacuum dessicator. To the dried salt anhydrous dimethylformamide (20 ml) and N-2-bromoethyl)phthalimide (0,01505 mol) were added and the mixture was refluxed for 6 hours. After cooling to ambient temperature water (100 ml) was added to the reaction mixture. The product was filtrated and purified by recrystallization.2-[2-(l-Oxo-leta-phthalazin-2-yl)-ethyl]-isoindole-l,3-dione (compound no. 9)
As the paragraph descriping shows that 119-39-1 is playing an increasingly important role.
