반응 단계

To 4,7-difluoroisobenzofuran-1,3-dione (1.00 g, 5.43 mmol) and sodium acetate (0.535 g, 6.52 mmol) was added water (14 mL), acetic acid (7.15 ml, 125 mmol) and hydrazine (0.205 ml, 6.52 mmol)(slowly). A water condenser was attached and the mixture was heated to reflux for 20 hours. Cooled to RT and filtered the resulting solid. Washed with water and dried to yield 5,8-difluoro-2,3-dihydrophthalazine-1,4-dione as a white solid.
