실험 절차

16.52 g of phenylalanine was dissolved in a solution of 10 g of concentrated sulfuric acid, 20 mL water, 20 mL of dodecanol, and 120 mL of toluene in a 500 mL round bottom flask equipped with a condenser and a Dean-Stark apparatus. The resulting solution was heated at reflux temperature until no more water could be distilled. The resulting solution was then cooled to room temperature and washed with saturated aqueous sodium bicarbonate to neutralize acidic impurities, washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was then removed under reduced pressure to provide phenylalanine dodecanoate as a solid that was purified using a silica gel column eluted with a 1:9 methanol:dichloromethane mixture.
