実験手順
A stirred mixture of 2,3-bishydrazinocarbonyl-5-bromo-7-ethyl-4-hydroxyquinoline (0.40 g, 1.1 mM) in glacial acetic acid (12 mL) was heated at 81° C. for 1.5 hr. After cooling to room temperature, the reaction mixture was filtered and the collected solids washed with acetic acid and air dried to provide the title compound (0.25 g, 70%) as a light brown solid, mp>400° C.; MS(CI): 336 (M+H).
