1.36 g (8.8 mmol) of optically active 1,2-epoxy-9-decene and 6 ml of THF were injected, and they were cooled to -17° C. Then, 9-borabicyclo [3.3.1]nonane (0.5M THF solution) was dripped, and stirring at 0° C. was performed for one hour. Then, stirring at room temperature was performed for one hour, and then 0.26 g (0.073 mmol) of tetrakis (triphenylphosphine) palladium, 3.00 g (8.00 mmol) of 5-decyl-2-(4-bromophenyl) pyrimidine, 10 ml of DMF, and 2.21 g (16.0 mmol) of potassium carbonate were added, and stirring at 60° C. was performed for 5 hours. After reactions had been completed, water was added, and extraction with ethyl acetate was performed. The extracted solution was dried, and then the solvent was removed by filtration. Then, refining was performed with a silica gel column chromatography (developing solvent: toluene/ethyl acetate=50/1) and by recrystallization (toluene/methanol) so that 2.10 g of 1,2-epoxy-8-{4-(5-decylpyrimidine-2-yl) phenyl}decane was obtained (yield 58%).
