Reaction Conditions

Reaction Steps

The product from Example 58C (0.90 g, 2.50 mmol) was dissolved in ethanol (20 mL). A solution of lithium hydroxide (0.57 g, 23.97 mmol) in water (5 mL) was added, and the reaction was heated to 80° C. for 2 hours. The reaction mixture was cooled to room temperature, concentrated, neutralized with 2 N HCl, and then extracted with ethyl acetate. The organic layer was washed with water and brine, dried over magnesium sulfate, filtered, and concentrated to supply the title compound. MS (APCI+) m/z 332.2 (M+H)+.
