Procedure

A solution of the product of Example 19 (0.80 g) in ethanol (30 ml) containing 40% sodium hydroxide solution (2.0 ml) was heated under reflux for 2 hours and then evaporated. Water was added to the residue and the mixture was extracted several times with ethyl acetate. The combined organic extracts were dried (MgSO4) and evaporated to give a gum. The gum was dissolved in ether and the title compound, (0.45 g), crystallised on standing, m.p. 182°-185°.
