1242156-59-7, 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1-(2-Formyl-3-iodophenyl)-3-(4-(morpholine-4-carbonyl)phenylamino)-1H-pyrazole-4-carbonitrile (115 mg, 0.218 mmol), 6-tert-butyl-8-fluorophthalazin-1(2H)-one (48 mg, 0.218 mmol), cuprous iodide (41.5 mg, 0.218 mmol) and sodium bicarbonate (36.6 mg, 0.436 mmol) were combined in 2 mL of DMSO. The mixture was thoroughly degassed with argon and stirred in an oil bath preheated to 100 C. for 1 hr. The mixture was extracted with dichloromethane and water. The organic layer was washed with brine, dried over sodium sulfate and filtered. Solvents were evaporated and the residue was purified by flash column chromatography using methanol in dichloromethane (0% to 5% in 16 minutes, 24 g silica gel) to give 1-[3-(6-tert-butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-2-formyl-phenyl]-3-[4-(morpholine-4-carbonyl)-phenylamino]-1H-pyrazole-4-carbonitrile as a pale pink solid (54 mg, 40% yield). LC/MS clacd for C34H30FN7O4 (m/e) 619.23, obsd 620.0 (M+H, ES+); 1H NMR (400 MHz, CDCl3) delta ppm 1.43 (s, 9H), 3.56-3.76 (m, 8H), 6.61 br. s., 1H), 7.40 (d, J=8.6 Hz, 2H), 7.46 (d, J=8.6 Hz, 2H), 7.52 (dd, J=12.4, 1.8 Hz, 1H), 7.55-7.59 (m, 2H), 7.64 (d, J=7.8 Hz, 1H), 7.78 (t, J=8.1 Hz, 1H), 8.16 (s, 1H), 8.32 (s, 1H), 9.97 (s, 1H)., 1242156-59-7
As the paragraph descriping shows that 1242156-59-7 is playing an increasingly important role.
