実験手順
To a solution of 3-acetamido-6-acetoxy-3-[2-(4-octanoylphenyl)ethyl]hexyl acetate (720 mg) in triiluoroacetic acid (15 ml), triethylsilane (0.53 ml) was added at room temperature. After stirring for an hour, the reaction solution was poured into ice-water and potassium carbonate was carefully added to the mixture to neutralize. The mixture was extracted with ethyl acetate and the extract was washed with water and a saturated brine and dried over anhydrous magnesium sulfate. The solvent was distilled away and the residue obtained was purified by silica gel chromatography (eluent; hexane-ethyl acetate=1:1) to give the subject compound (450 mg) as a colorless oily substance.
