1-(3-bromophenyl)ethane-1,2-diamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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%). First, into a 500-mL three-neck flask were put A reaction container was heated the reacted solution was refluxed for two hours the mixture was refluxed for nine hours Then, the obtained mixture was subjected to suction filtration washed with ethanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

The solution in the flask was refluxed for 2 hours, 2.1 g of 9,10-phenanthrenequinone was added thereto, and the solution was refluxed for 9 hours. After that, the obtained mixture was suction-filtered, and the resulting solid was washed with ethanol to give 2-(3-bromophenyl)dibenzo[f,h]quinoxaline as a yellow-white solid in a yield of 70%.
