Procedure

13.1 g of isoleucine was dissolved in a solution of 10 g of concentrated sulfuric acid, 20 mL water, 20 mL of octanol, and 200 mL of toluene in a 500 mL round bottom flask equipped with a condenser and a Dean-Stark apparatus placed in an oil bath. The resulting solution was heated at reflux temperature until no more water could be distilled. The resulting solution was then cooled to room temperature, diluted with 120 mL of ethyl acetate and the organic layer washed with saturated aqueous sodium bicarbonate to neutralize acidic impurities, washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure and the resulting liquid distilled to provide isoleucine octanoate as a colorless liquid.
