Reaction Conditions

Reaction Steps

To a suspension of anhydrous aluminum chloride (1.4 g) in 1,2-dichloroetane (20 ml), octanoyl chloride was carefully added at room temperature and the suspension was stirred until anhydrous aluminum chloride was entirely dissolved. To the reaction solution, a solution of 3-acetamido-6-acetoxy-3-(2-phenylethyl)hexyl acetate (780 mg) in 1,2-dichloroethane (10 ml) was dropwise added at room temperature over 10 minutes. The reaction temperature raised to 70° C. and the mixture was stirred for 30 minutes. After cooling, the reaction solution was poured into ice-water and extracted with chloroform. The chloroform layer was washed with water and a saturated brine, dried over anhydrous magnesium sulfate and the solvent was distilled away. The residue obtained was purified by silica gel chromatography (eluent; hexane-ethyl acetate=1:1) to give the subject compound (780 mg) as a yellowish oily substance.
