Name is 6-Bromophthalazin-1(2H)-one, as a common heterocyclic compound, it belongs to phthalazine compound, and cas is 75884-70-7, its synthesis route is as follows.,75884-70-7
To a suspension of 6-bromophthalazine-l-(2H)-one (563 mg, 2.5 mmol) in DMF (25 mL) under an argon atmosphere was added sodium hydride (140 mg of 60% oil dispersion, 3.5 mmol) and the resulting mixture was allowed to stir at room temperature for 15 min. before addition of (2-(chloromethoxy)ethyl)trimethylsilane (0.53 mL, 3 mmol). The reaction mixture was stirred at room temperature overnight, then poured onto water and ether and extracted with ether (3X). The combined organic layer was washed with water, then brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was slurried in DCM and filtered. The solid was washed with DCM. The combined filtrate and wash was purified by chromatography to provide 6-bromo-2-((2-(trimethylsilyl)ethoxy)methyl)phthalazin-l(2H)-one (625 mg, 70% yield) as a white solid. NMR (300 MHz, Chloroform-^ delta 8.37 – 8.29 (m, 1H), 8.12 (s, 1H), 7.93 – 7.85 (m, 2H), 5.57 (s, 2H), 3.84 – 3.62 (m, 1H), 1.10 – 0.89 (m, 1H), 0.01 (s, 9H).
With the complex challenges of chemical substances, we look forward to future research findings about 6-Bromophthalazin-1(2H)-one
