참여 물질

반응 단계

To a solution of 4-benzyloxybenzoic acid chloride (1.1 g) in methylene chloride (20 ml) was slowly added under ice cooling a solution of optically active 1,1,1-trifluoro-2-octanol (0.74 g, [α]D20 =+25.2) and triethylamine (0.4 g) in methylene chloride (10 ml). After the solution was left to stand to reach room temperature, it was stirred for 12 hours. The solution was poured in ice water and was extracted with methylene chloride. The extracted layer was washed with dilute aqueous hydrochloric acid solution, water, 1N aqueous sodium carbonate solution and water, in the order, and dehydrated over anhydrous magnesium sulfate. The solution was distilled under reduced pressure to remove the solvent until a crude product was obtained. The product was subjected to silica-gel column chromatography to obtain 1,1,1-trifluoro-2-octyl 4-benzyloxybenzoate (0.73 g).
