As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO250,mainly used in chemical industry, its synthesis route is as follows.,119-39-1
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
With the complex challenges of chemical substances, we look forward to future research findings about Phthalazin-1(2H)-one,belong phthalazine compound
