Procedure

4 g of tryptophane butanoate hydrochloride salt (commercially available from Sigma-Aldrich, St. Louis, Mo. (www.sima-aldrich.com)) was suspended in 100 mL of dichloromethane and 3 ml of triethylamine was added to the suspension with stirring. Stirring was continued for 15 min and the resulting solution was transferred to a separatory funnel. The organic solution was washed twice with 25 mL of water followed by 25 mL of saturated aqueous sodium bicarbonate. The organic layer was then dried over anhydrous sodium sulfate and concentrated under reduced pressure to provide tryptophane octanoate. The structure was confirmed using mass spectroscopy.
