Procedure

To a solution of 3-acetamido-6-acetoxy-3-[2-(4-octylphenyl)ethyl]hexyl acetate (400 mg) in methanol-water (1:1) (12 ml), lithium hydroxide monohydrate (360 mg) was added at room temperature and the mixture was refluxed under heating for 4 hours. After cooling, the mixture was neutralized with ammonium chloride and the solvent was distilled away under reduced pressure. The residue obtained was extracted with chloroform, the extract was washed with water and a saturated brine and dried over anhydrous magnesium sulfate. The solvent was distilled away to give the subject compound (290 mg) as a yellowish oily substance.
