Procedure
To a solution of 23 (0.6 g, 1.7 mmol) in dioxane (8 ml) 20% NaOH is added (13 ml) and the mixture is refluxed for 1.5 hours. The solvent is concentrated under reduced pressure and the aqueous phase is added with 20% NaOH to pH=7. The resulting solid is filtered under reduced pressure, washed with water and dried to give compound 24 as white solid (0.43 g, 83% yield).
