As a common heterocyclic compound, it belongs to phthalazine compound, name is Phthalazin-1(2H)-one, and cas is 119-39-1, its synthesis route is as follows.,119-39-1
A mixture of 4-(2-bromoethoxy)benzaldehyde (4.97g), 1(2H)-phthalazinone (3.27 g), potassium carbonate (6.20 g) and N,N-dimethylformamide (50 ml) was stirred at 80C for 5 hours. After cooling, the reaction mixture was poured into water, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4) and concentrated to obtain 4-[2-[1-oxo-2(1H)-phthalazinyl]ethoxy]benzaldehyde (5.36 g, yield 84%) as colorless crystals. This was recrystallized from ethyl acetate-hexane. Melting point: 126-127C
With the complex challenges of chemical substances, we look forward to future research findings about 119-39-1,belong phthalazine compound
