実験手順
A solution of N-Ac-D-Phe-2-Nal-OMe (1.55 g) in 20 ml of dioxane/water=9/1 (v/v) was treated with sufficient 6N sodium hydroxide to keep the pH at 12 for 1 hours at room temperature. After acidification, the mixture was poured into water and was extracted with dichloromethane. The organic layer was washed with water and was dried on sodium sulfate. The filtrate was evaporated and yielded 1.7 g crude N-Ac-D-Phe-2-Nal-OH.
