Reaction Steps

Into a 200 mL three-neck recovery flask, 2.4 g (5.0 mmol) of 5,6-bis(4-bromophenyl)-3-(3-pyridyl)-1,2,4-triazine, 60 mL of para-xylene, and 2.5 mL (23 mmol) of 2,5-Norbornadiene were put. This solution was refluxed at 150° C. for 20 hours under a nitrogen stream. After a certain time, water was added to the mixture, and an aqueous layer was extracted with toluene. The obtained extract was washed with a saturated saline together with an organic layer and the organic layer was dried over magnesium sulfate. The mixture was subjected to gravity filtration, and the obtained filtrate was concentrated to give a solid. The obtained solid was refined with silica gel column chromatography (hexane:ethyl acetate=1:1) and recrystallized with chloroform/hexane, so that an objective substance, 0.68 g of yellow powder was obtained in a yield of 28%.
