実験手順
A mixture of 2-(2-(6-oxo-3-phenylpyridazin-1(6H)-yl)ethyl)isoindoline-1,3-dione (2.1 g, 6.1 mmol) and hydrazine (10 mL, 10.0 mmol) (THF) in MeOH (40 mL) was heated to 75° C. A clear solution was formed. After overnight (18 h), the slurry was cooled to room temperature and was filtered and washed with MeOH. The filtrate was concentrated and washed with 20% MeOH/CH2Cl2 to give a yellow solid (LCMS indicated the presence of product). The filtrate was concentrated under vacuum and was carried to next step.
