실험 절차

TMSCl (1.27 mL, 10 mmol) was added at room temperature to a solution of NaI (1.50 g, 10 mmol) in CH3CN (60 mL). After stirring for 30 min, 1-(2-fluorophenyl)-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-4(1H)-one (0.725 g, 2 mmol) was added to the resulting suspension. The mixture was stirred for 30 min at room temperature and then refluxed for 1 h. After cooling to room temperature, the reaction mixture was poured into water and extracted with AcOEt. The extract was washed with brine, dried over MgSO4, and concentrated under reduced pressure. The residue was washed with hexane/AcOEt (1/1) and recrystallized from MeOH/H2O to give the title compound (0.648 g, 93% yield) as off-white prisms: mp 218-220° C.; NMR (300 MHz, DMSO-d6): δ ppm 6.99 (1H, d, J=1.9 Hz), 7.10 (1H, dt, J=1.5, 7.9 Hz), 7.21-7.26 (1H, m), 7.32-7.54 (7H, m), 7.80 (1H, d, J=1.9 Hz), 8.44 (1H, d, J=2.6 Hz). Anal. Calcd for C19H13FN4O2: C, 65.51; H, 3.76; N, 16.08. Found: C, 65.73; H, 3.88; N, 16.24.
