763111-47-3, 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A reaction mixture of amine precursor (51 mg, 0.139 mmol), 4-carboxylphenylboronic acid pinacol ester (38 mg, 0.153 mmol), HATU (60 mg, 0.158 mmol) and DIPEA (50 muL) in DMF (1 mL) was stirred at room temperature overnight. Water (10 mL) was added, and precipitate was filtered and rinsed with water, and then dissolved in ethyl acetate. After drying by magnesium sulfate, the solution was concentrated under reduced pressure. The residue was purified by silica gel chromatography to afford final product (37 mg) as white solid. M.P.: 288-291 C; 1H NMR (400MHz, CDCl3) delta 10.66 (s, 1H), 8.47 (s, 1H), 7.85-7.72 (m, 5H), 7.38-7.33 (m, 4H), 7.04 (m, 1H), 4.29 (s, 2H), 3.73 (m, 4H), 3.37 (m, 4H), 1.35 (s, 9H), 1.27 (s, 3H). 13C NMR (100MHz, CDCl3) delta 160.4, 145.5, 142.2, 135.0, 134.4, 133.7, 131.6, 129.5, 129.2, 128.3, 127.2, 126.1, 125.0, 121.5, 84.1, 37.7, 29.7, 24.8; HRMS m/z: calcd for C33H34BFN4O5+H, 597.2679; found 579.2661.
