실험 절차
To a mixture of 3,4-dibromo-5-p-tolylfuran-2(5H)-one (0.5 g, 1.506 mmol) in ethanol (5 mL) was added NH2NH2 (0.047 mL, 1.506 mmol) at 0° C. The mixture was stirred at room temperature overnight. The precipitate was filtered and dried under reduced pressure to give the title compound as a beige solid (0.22 g). LCMS m/z=264.9 [M+H]+.
