Procedure

A mixture of 3-fluoro-4-[5-methoxy-4-oxo-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-1(4H)-yl]phenyl trifluoromethanesulfonate (459 mg, 0.9 mmol), 3,6-dihydro-2H-pyran-4-boronic acid pinacol ester (210 mg, 1.0 mmol), Pd(PPh3)4 (52 mg, 0.045 mmol), Na2CO3 (212 mg, 2.0 mmol), DME (4 mL), and H2O (1 mL) was refluxed overnight under Ar atmosphere. After cooling to room temperature, the precipitate was collected by filtration and recrystallized from THF/MeOH to give the title compound (364 mg, 91% yield) as a white solid: mp 229-231° C.; 1H NMR (300 MHz, DMSO-d6): δ ppm 2.40-2.50 (2H, m), 3.77 (3H, s), 3.82 (2H, t, J=5.5 Hz), 4.22-4.27 (2H, m), 6.43-6.48 (1H, m), 6.97 (1H, d, J=1.9 Hz), 7.02 (1H, t, J=8.7 Hz), 7.29-7.46 (6H, m), 7.52 (1H, dd, J=1.9, 12.8 Hz), 7.79 (1H, d, J=1.9 Hz), 8.48 (1H, d, J=1.9 Hz). LC-MS (ESI) m/z 445 [M+H]+. Anal. Calcd for C25H21FN4O3: C, 67.56; H, 4.76; N, 12.61. Found: C, 67.31; H, 4.58; N, 12.52.
