実験手順
A mixture of methyl 1-[2-(benzyloxy)-4-(3,4-difluoro-1H-pyrrol-1-yl)phenyl]-5-methoxy-4-oxo-1,4-dihydropyridazine-3-carboxylate (4.54 g), 1M aqueous sodium hydroxide solution (15 mL), THF (30 mL) and methanol (30 mL) was stirred at room temperature for 30 min. The reaction mixture was neutralized with 1M hydrochloric acid, and the precipitate was collected by filtration, and washed with water to give the title compound (0.5 THF solvate, 4.70 g).
