Triethylamine → (R)-(+)-1,1,1-trifluoro-2-octyl 4-benzyloxybenzoate

Participants

Reaction Steps

To 5 ml of a methylene chloride solution containing 0.56 g of 4-benzyloxybenzoic acid chloride was slowly added a solution of 0.38 g of (R)-(+)-1-trifluoromethylheptanol and 0.23 g of triethylamine in 5 ml of methylene chloride under ice-cooling. The mixture was allowed to warm to room temperature and stirred at that temperature for 12 hours. The reaction mixture was poured into ice-water and extracted with methylene chloride. The methylene chloride phase was washed successively with diluted hydrochloric acid, water, an aqueous 1N sodium carbonate solution, and water and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and the residual crude product was purified by silica gel column chromatography to obtain 0.53 g of (R)-(+)-4-benzyloxybenzoic acid 1-trifluoromethylheptyl ester.
