20 parts of 2-iodofluorene was dissolved in a mixed solution of 114 parts of dimethyl sulfoxide (DMSO) and 23 parts of tetrahydrofuran (THF), and the thus obtained mixture was then stirred at 25° C. for 10 minutes. Thereafter, while stirring, 8.7 parts of potassium-tert-butoxide was added to the mixture. Twenty minutes later, 19.2 parts of n-octyl iodide was added to the mixture, and further twenty minutes later, 8.7 parts of potassium-tert-butoxide was added thereto. Further, twenty minutes later, 19.2 parts of n-octyl iodide was added thereto, and the obtained mixture was then stirred at 25° C. for 2 hours. After completion of the stirring, THF was distilled away from the reaction solution, and it was then extracted with toluene-water. The toluene phase was dried over magnesium sulfate, and the toluene was then distilled away, thereby obtaining a brown tarry solid. This brown tarry solid was separated and purified by column chromatography (hexane-ethyl acetate) to obtain 30 parts of 9,9-di-n-octyl-2-iodofluorene in the form of a colorless crystal.
