Versuchsvorschrift

In a round bottom flask, oleic acid (1) (1.53 g, 5.33 mmol) was dissolved in 20 ml of dry pyridine (over KOH). To the solution TEA (0.74 ml, 5.33 mmol), DCC (1.1 g, 5.33 mmol), and NHS (0.55 g, 4.85 mmol) were added. The mixture was stirred at room temperature for overnight. After confirming the total conversion of the acid to the NHS intermediate using TLC (5% MeOH), L-Valinol (0.5 g, 4.85 mmol) was added and the mixture was stirred for additional 24 hours. After completion of the reaction (TLC: 100% Ethyl acetate), volatiles were removed under reduced pressure to dryness. The gum was dissolved in 5 ml DCM and the desired product oleoyl-valinol (10) was obtained using column chromatography (dichloromethane/ethyl acetate=1:1, v/v)). Colorless viscous oil (0.94 g, 46.8 yield).
