Procedure

To a solution of Example 56A (2.5 g, 12.6 mmol) in methanol/water (1:1, 100 mL) was added 5 N aqueous NaOH (3.8 mL, 19 mmol). The mixture was stirred at room temperature for 3 hours and then extracted with methylene chloride to remove unreacted starting material. The aqueous layer was acidified (pH˜2) with 6 N aqueous HCl and then extracted with methylene chloride. The combined acidic extracts were dried (Na2SO4), filtered and concentrated to afford 1.92 g of the title compound. MS (ESI+) m/z 183 (M+H)+.
