実験手順
[2-(1,3-dioxo-1,3-dihydroisoindol-2-yloxy)-ethyl]-carbamic acid tert-butyl ester (0.842 g, 2.749 mmol) was dissolved in 20 ml of CH2Cl2 and methylhydrazine (150 μL, 2.776 mmol) was added at room temperature. As soon as methylhydrazine was added, a white precipitate was formed. The reaction was stirred at room temperature for 72 hours. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure to provide 0.496 g of a viscous oil (102% yield). The crude material was used without further purification.
