実験手順
To a solution of Example 54A (2.5 g, 12.6 mmol) in methanol/water (1:1, 100 mL), 5 N aqueous NaOH (3.8 mL, 19 mmol) was added. The mixture was stirred at room temperature for 3 hours and then extracted with dichloromethane to remove un-reacted starting material. The aqueous layer was acidified (pH˜2) with 6 N aqueous HCl and then extracted with dichloromethane. The combined acidic extracts were dried (Na2SO4), filtered, and concentrated under reduced pressure to afford 1.92 g of the title compound. MS (ESI+) m/z 183 (M+H)+
