5788-58-9, 4,5-Dibromopyridazin-3(2H)-one is a pyridazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5788-58-9
To a stirred solution of 4,5-dibromo-2,3-dihydropyridazin-3-one (60 mg, 0.238 mmol, 1 equiv.) and DIEA(61.5 mg, 0.476 mmol, 2 equiv.) in DMA(3 mL) was added 1-(2,2,2- trifluoroethyl)piperazine (48 mg, 0.286 mmol, 1.2 equiv.) in portions at 100 degrees C for 1.5 hours. The reaction liquid was purified by Prep-HPLC with the following conditions (Column: XBridge Prep C18 OBD Column 19X150mm 5um; Mobile Phase A: Water(10 mmol/L (0289) NH4HCO3), Mobile Phase B: MeCN; Flow rate: 20 mL/min; Gradient: 20% B to 45% B in 7.5 min; 254/220 nm; Rt: 7.17 min) to afford 4-bromo-5-[4-(2,2,2-trifluoroethyl)piperazin-1-yl]-2,3- dihydropyridazin-3-one (12.3 mg, 15.26%) as a white solid
As the paragraph descriping shows that 5788-58-9 is playing an increasingly important role.
