Reaction Steps
A mixture of 2,7-dibromophenanthrene-9,10-dione (1.0 g, 2.7 mmol), ethylenediamine (1.8 mL, 26.9 mmol) and ethanol (20 mL) was heated to 85° C. After 3 hours, the reaction was cooled to room temperature and the solids were filtered and thoroughly washed methanol to yield 6,11-dibromodibenzo[f,h]quinoxaline (360 mg, 34%).
