반응 단계

To a solution of 4-benzyloxybenzoic acid chloride (4.3 g) in methylene chloride (50 ml) was slowly added under ice cooling a solution of optically active 1,1,1-trifluoro-2-octanol (2.9 g), dimethylaminopyridine (0.6 g) and triethylamine (1.7 g) in methylene chloride (50 ml). The mixture was left to stand until it reached room temperature and allowed to react overnight. The mixture was poured in ice water and extracted with methylene chloride. The extracted layer was washed with dilute aqueous hydrochloric acid solution, water, 1N aqueous sodium carbonate solution and water, in this order, and dried over anhydrous magesium sulfate. After the solution was distilled to remove the solvent, the crude product obtained was purified by silica-gel column chromatography and recrystallized from ethanol to obtain the titled compound (3.8 g).
