Procedure

In a 200 mL three-neck flask were put 2.4 g (5.0 mmol) of 5,6-bis(4-bromophenyl)-3-(pyrimidin-2-yl)-1,2,4-triazine, 60 mL of para-xylene, 2.1 mL (19 mmol) of 2,5-Norbornadiene, and the mixture was refluxed under a nitrogen gas stream at 150° C. for 12 hours. After a certain time, water was added to the mixture, and an aqueous layer was extracted with toluene. The extract was washed with a saturated saline together with the organic layer, and the organic layer was then 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 recrystallized with chloroform/hexane, so that 1.6 g of a target substance, light-yellow solid was obtained in a yield of 67%.
