Versuchsvorschrift

To a cooled (0° C.) suspension of the compound of Example 43 (10.0 g, 24 mmole) in methanol (50 mL) is added 1.0N NaOH (49 mL) over a period of 10 minutes. After the addition is complete, the solution is allowed to warm to room temperature over a period of 1.5 hours. The solvent is reduced under vacuum, residue diluted with water, and washed with ethyl acetate twice. The aqueous layer is acidified with 2.0N HCl to pH 1, extracted with ethyl acetate three times. The combined organic extracts are washed with water, then brine (twice). The solvent is removed to give the title compound.
