0.40 g (1.46 mM of 2-octylindan-5-boronic acid, 0.60 g (1.30 mM) of 3-fluoro-4-(5-decylpyrimidine-2-yl)phenyl triflate, 1.2 ml of ethanol, 2 ml of toluene, 2 ml of 2M-sodium carbonate aqueous solution and 0.07 g of tetrakis (triphenylphosphine) palladium (O) were mixed and heat-refluxed for 200 minutes 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. The residue was purified by silica gel column chromatography (eluent: toluene/ethyl acetate=100/1) and treated with activated carbon, followed by recrystallization from acetone to obtain 0.52 g of 2-octyl-5-[3-fluoro-4-(5-decylpyrimidine-2-yl)phenyl]indan (Yield: 73.8%). ##STR316##
