Reaction Steps

2-[(3-Oxo-2,3-dihydropyridazin-4-yl)methyl]isoindoline-1,3-dione (255 mg, 1.00 mmol) in methanol (2 mL) was mixed with hydrazine monohydrate (250 mg, 5.00 mmol) at room temperature and stirred at 60° C. for 3 hours. After completion of the reaction, the solid was filtered off with chloroform, and the filtrate was evaporated under reduced pressure repeatedly to give a crude reaction product containing the desired product, which was used for the next step.
