There was washed 1.50 g (11.22 mmol) of potassium hydride having a purity of 30% by weight with each 3 mL of hexane three times in an atmosphere of nitrogen, and 18 mL of THF was added thereto. To the obtained THF slurry of potassium hydride, 2.50 g (8.98 mml) of 3,6-di-tert-butylfluorene was added dropwise at 0° C. using 18 mL of a THF solution thereof. The obtained mixture was stirred for 2 hours at a room temperature, and then 2.92 g (8.98 mmol) of (2-allyloxy-3-tert-butyl-5-methylphenyl)chlorodiethylsilane was added dropwise at −78° C. using 4 mL of a toluene solution thereof. The temperature of the obtained liquid reaction mixture was raised up to a room temperature, and the mixture was stirred for 2 hours. The mixture was added dropwise at 0° C. to a mixture of 18 mL of a 10% aqueous solution of sodium hydrogen carbonate and 18 mL of a 10% aqueous solution of sodium carbonate, and the resultant mixture was extracted with 10 mL of toluene. The obtained extract was dried over sodium sulfate, and dried extract was concentrated under a reduced pressure, thereby obtaining quantitatively (2-allyloxy-3-tert-butyl-5-methylphenyl)(3,6-di-tert-butylfluoren-9-yl)diethylsilane.
