To a solution of 4-benzyloxybenzoic acid chloride (1.23 g) in methylene chloride (10 ml) was added by little and little under ice-cooling a solution of optically active 1,1,1-trifluoro-2-decanol (0.96 g), dimethylaminopyridine (0.55 g) and triethylamine (0.48 g) in methylene chloride (20 ml). The mixture was left to stand overnight at room temperature in order to effect a reaction before the mixture obtained was poured in ice-water. Extraction was effected with methylene chloride and the extracted phase was washed with dilute aqueous hydrochloric acid solution, water, 1N aqueous sodium carbonate solution and water in due order before it was dried over anhydrous magnesium sulfate. The solvent was distilled off to obtain a crude product which was purified by toluene/silica from ethanol to obtain the titled compound (1.84 g).
