6-Bromophthalazine, cas is 19064-74-5, it is a common heterocyclic compound, the phthalazine compound, its synthesis route is as follows.,19064-74-5
A mixture of 6-bromophthalazine (0.11 g, 0.50 mmol), 6-chloro-N-methyi-N-(2,2,6,6-tetramethylpiperidin-4-yl)pyridazin-3-amine (0.16 g, 0.58 mmol), 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2’bi(1 ,3,2-dioxaborolane) (0.14 g, 0.55 mmol), potassium acetate (0.15 g, 1.5 mmol) and [1, 1 ‘bis(diphenylphosphino)ferrocene]dichloropalladium(ll), complex with dichloromethane (0.04 g, 0.05mmol) in dioxane (3 ml) was heated at 80 oc for 3 h. Potassium carbonate (0.20 g, 1.5 mmol) and10 water (0.4 ml) were added and the mixture was stirred for 48 hat 90 C. After cooling, the reactionwas purified by solid phase extraction (SiliaBond Carbonate, MeOH as eluent). After evaporationof the solvent under reduced pressure, the material afforded was purified via reverse phasepreparative HPLC using 5 to 95% acetonitrile in water modified with 3% n-PrOH. LCMS: Rt = 0.43min [M+H] (LCMS method Q); 377.245; 1H NMR (400 MHz, DMSO-d6) o 9.74-9.62 (m, 2H), 8.7515 (s, 1H), 8.74 (dd, J= 8.5, 2.0 Hz, 1H), 8.23 (d, J= 8.5 Hz, 1H), 8.12 (d, J= 9.5 Hz, 1H), 7.19 (d, J=9.5 Hz, 1H), 5.19 (tt, J= 12.0, 3.5 Hz, 1H), 2.98 (s, 3H), 1.56 (dd, J= 12.0, 3.5 Hz, 2H), 1.45 (t, J=12.0 Hz, 2H), 1.27 (s, 6H), 1.10 (s, 6H).
19064-74-5 is used more and more widely, we look forward to future research findings about 6-Bromophthalazine
