Procedure

Into a 100 mL three-neck flask, 2.2 g (4.7 mmol) of 5,6-bis(4-bromophenyl)-3-(4-pyridyl)-1,2,4-triazine, 45 mL of para-xylene, 2.5 mL (23 mmol) of 2,5-Norbornadiene were put, and the solution was stirred at 140° C. for 14 hours under a nitrogen stream. After a certain time, water was added to the solution, and an aqueous layer was extracted with chloroform. The obtained extract was washed with a saturated saline together with the organic layer and then dried over magnesium sulfate. The obtained 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=2:1), so that 1.7 g of a target substance, yellow powder was obtained in a yield of 78%.
