Procedure

The product of Example 25, of structure XXIX (620 mg, 2.0 mmol) was dissolved in aqueous NaOH (2 M, 4 mL) and stirred at room temperature for 1 hour. The reaction was quenched by adding 6 N HCl to give pH 4 to 5. The solution was diluted with 95% ethanol, separated from the precipitated salts and evaporated to give 540 mg.
