الإجراء التجريبي

300 μL of 1 N sodium hydroxide solution (300 μmol) are added portionwise to 48 mg of 25 (157 μmol) in methanol (2 mL). The solution is refluxed for 1 hour 30 minutes. After evaporating off the solvent, the reaction medium is acidified with 0.5 N HCl and extracted with DCM. 45 mg of a pale yellow oil are obtained, i.e. a yield of 99%.
