Reaction Steps

A suspension of 1-[4-(3,4-difluoro-1H-pyrrol-1-yl)-2-hydroxyphenyl]-5-methoxy-3-(1-phenyl-1H-pyrazol-5-yl)pyridazin-4(1H)-one (231 mg), iodomethane (0.0375 mL) and potassium carbonate (138 mg) in DMF (2.5 mL) was stirred at room temperature overnight. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (NH, THF), and recrystallized from methanol/water to give the title compound (232 mg).
