As a common heterocyclic compound, it belong phthalazine compound,6-Bromophthalazine,19064-74-5,Molecular formula: C8H5BrN2,mainly used in chemical industry, its synthesis route is as follows.,19064-74-5
A glass microwave reaction vessel was charged with 6-bromophthalazine (1.0 g, 5 mmol), tert-butyl 5-(tributylstannyl)thiazol-2-ylcarbamate (4.0 g, 7 mmol), DMF (4 mL), cesium fluoride (1.0 g, 10 mmol), copper(I) iodide (0.2 g, 1.0 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.3 g, 0.2 mmol). The reaction mixture was stirred and heated at 100 C. overnight. The mixture was diluted with DCM (20 mL) and water (5 mL) and filtered through Celite. The organic solution was evaporated under reduced pressure, and the residue was adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep pre-packed silica gel column (40 g), eluting with a gradient of 5% to 10% MeOH in DCM to provide the title compound (1.19 g, 76%). LCMS (M+H+) 329.3 calc. for C16H16N4O2S 329.3; 1H NMR (400 MHz, CDCl3) delta ppm 9.50 (s, J=13.69 Hz 1H), 9.46 (s, 1H), 8.01 (d, J=1.37, Hz 1H), 7.92 (d, J=8.41 Hz, 1H), 7.81 (s, 1H), 7.58 (s, 1H) 1.40 (s, 9H).
With the synthetic route has been constantly updated, we look forward to future research findings about 6-Bromophthalazine,belong phthalazine compound
