0.55 g (2.01 mM of 2-octylindan-5-boronic acid, 0.80 g (1.81 mM) of 4-(4-decylphenyl)phenyl triflate, 1.5 ml of ethanol, 2.8 ml of toluene, 2.8 ml of 2M-sodium carbonate aqueous solution and 0.09 g of tetrakis(triphenylphosphine)palladium (O) were mixed and heat-refluxed for 4 hours under stirring. After the reaction, the reaction mixture, water and toluene were added to followed by filtration under reduced pressure. The toluene layer was washed with a common salt aqueous solution followed by drying with anhydrous sodium sulfate. Then, the sodium sulfate was removed from the mixture and the resultant mixture was evaporated to obtain a residue. Ethyl acetate was added to the residue and cooled with ice water to precipitate a crystal. The crystal was recovered by filtration and purified by silica gel column chromatography (eluent: toluene) and recrystallized from a mixture solvent (toluene/ethyl acetate). The resultant crystal was further purified by silica gel column chromatography (eluent: toluene/hexane=2/1) and recrytallized from a mixture solvent (toluene/hexane) to obtain 0.39 g of 2-octyl-5-[4-(4-decylphenyl)phenyl]indan (Yield: 41.3%). ##STR312##
