20 g (102 4 mmol) of 5H-phenanthridin-6-one, 43 g (112 mmol) of 2-(3-bromophenyl)-4,6-diphenyl-1,3,5-triazine, 2.3 g (10 2 mmol) of 1,3-bis[2-pyridyl]-1,3-propanedione, 28.3 g (204 mmol) of potassium carbonate and 1.9 g (10.2) of copper iodide are stirred under reflux in 1000 ml of DMF for 90 h. The solution is diluted with water and extracted twice with ethyl acetate, the combined organic phases are dried over Na2SO4, evaporated in a rotary evaporator and purified by chromatography (EtOAc/hexane: 2/3). The residue is recrystallised from toluene and from dichloromethane and finally sublimed in a high vacuum, purity is 99.9%. The yield is 31 g (62 mmol), corresponding to 61% of theory.
