119-39-1, Phthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of 3-(2-bromoethoxy)benzaldehyde (6.00 g), 1(2H)-phthalazinone (4.21 g), potassium carbonate (7.24 g) and N,N-dimethylformamide (40 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 3-[2-[1-oxo-2(1H)-phthalazinyl]ethoxy]benzaldehyde (6.94 g, yield 90%) as colorless crystals. This was recrystallized from acetone-hexane. Melting point: 110-111C
119-39-1 Phthalazin-1(2H)-one 8394, aphthalazine compound, is more and more widely used in various.
