Under a nitrogen atmosphere, 2-(3-octadecyloxy-2,2-bis-octadecyloxymethyl-propoxy)-9-fluorenone (75 mg, 73 μmol) was suspended in THF (1 ml) to allow dissolution at 50° C. 4-Chlorophenylmagnesium bromide solution (0.15 ml, 0.15 mmol) was added dropwise, and the mixture was stirred for 30 minutes. After completion of the reaction, the reaction mixture was cooled to room temperature, extracted with chloroform (3 ml), and washed 3 times with 1N hydrochloric acid (1 ml), 3 times with 5% NaHCO3 solution (1 ml) and once with 20% NaCl solution (1 ml). The organic layer was dried over Na2SO4, the solvent of the filtrate was evaporated, and the obtained residue was separated and purified by silica gel column chromatography and crystallized from methanol (1 ml) to give 2-(3-octadecyloxy-2,2-bis-octadecyloxymethyl-propoxy)-9-(4-chlorophenyl)-9-fluorenol (66 mg, 56μ mmol, 77%).
