실험 절차

A mixture of 1-[2-fluoro-4-(2-oxoimidazolidin-1-yl)phenyl]-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-4(1H)-one (40 mg, 0.09 mmol), iodomethane (0.02 mL, 0.36 mmol), and sodium hydride (60% in oil) (7.0 mg, 0.18 mmol) in DMF (4.0 mL) was stirred at 0° C. for 2 h. The reaction mixture was quenched with H2O, and extracted with AcOEt. The organic layer was dried over MgSO4, and concentrated under reduced pressure. The residue was recrystallized from iPr2O/AcOEt to give the title compound (24 mg, 59% yield) as a white solid: mp 208-209° C.; 1H NMR (300 MHz, DMSO-d6): δ ppm 2.79 (3H, s), 3.42-3.58 (2H, m), 3.77 (3H, s), 3.78-3.86 (2H, m), 6.95 (1H, d, J=1.9 Hz), 7.01 (1H, t, J=9.0 Hz), 7.22-7.51 (6H, m), 7.73 (1H, dd, J=14.1, 2.4 Hz), 7.78 (1H, d, J=1.9 Hz), 8.44 (1H, d, J=1.9 Hz). LC-MS (ESI) m/z 461 [M+H]+. Anal. Calcd for C24H21FN6O3.0.75H2O: C, 60.06; H, 4.49; N, 18.27. Found: C, 60.05; H, 4.26; N, 18.16.
