Versuchsvorschrift

First, into a 500-mL three-neck flask were put 2.5 g of 1-(3-bromophenyl)ethane-1,2-diamine, 0.62 g of potassium hydroxide, and 200 mL of dry ethanol, and the atmosphere in the flask was replaced with nitrogen. A reaction container was heated, the reacted solution was refluxed for two hours, 2.1 g of 9,10-phenanthrenequinone was added thereto, and the mixture was refluxed for nine hours. Then, the obtained mixture was subjected to suction filtration, and washed with ethanol, thereby obtaining 2-(3-bromophenyl)dibenzo[f,h]quinoxaline (a yellow white solid, a collection rate of 70%).
