Reaktionsschritte

Next, a reaction flask was loaded with acetic acid (54 ml) and 9,10-phenanthrenequinone (3.8 g), and the temperature was raised to 110° C. with stirring to dissolve 9,10-phenanthrenequinone. To this mixture, 2-hydrazino-6-(2,2,3,3,4,4,5,5-octafluoropentyloxy)pyridine (10 g) was added in 30 minutes. After stirring at 110° C. for one hour, the reaction mixture was filtrated. Crystals were stirred in methanol (100 ml) for 30 minutes, filtrated and dried to give intended crystals (5.2 g).
