To methylene chloride (20 ml) were added 2,3,5,6-tetrafluoroterephthalic acid chloride (0.27 g), (R)-(+)-1,1,1-trifluoro-2-decanol (0.1 g), triethylamine (0.05 g) and dimethylaminopyridine (0.02 g). After the mixture was left to stand for 8 hours in order to allow a reaction to proceed, 4-decyl-4'-hydroxybiphenyl (0.15 g) and triethylamine (0.05 g) were added thereto. The mixture was left for about 8 hours in order to allow a reaction to proceed, made acidic with 1N aqueous hydrochloric acid solution and extracted with methylene chloride. The extracted layer was washed with lN aqueous sodium carbonate solution, water, aqueous sodium chloride solution (saturated) and water, in this order, to make it neutral. The layer was dried over anhydrous magnesium sulfate and distilled under reduced pressure in order to remove the solvent. The solid product obtained was purified by silica-gel column chromatography to obtain the titled compound (0.14 g).
