Procedure
4 mL of 1 N sodium hydroxide solution (4.0 mmol) are added portionwise to 1.14 g of 15 (3.74 mmol) in methanol (30 mL). The solution is refluxed overnight. A further 4 mL of 1 N sodium hydroxide solution are added, and the mixture is refluxed for a further 1 hour 30 minutes. After evaporating off the solvent, the reaction medium is acidified with 0.5 N HCl and extracted with DCM. 1.04 g of a yellow oil are obtained, i.e. a yield of 96%.
