Reaction Conditions

Temperature80 °C

Reaction Steps

The product from Example 23C (0.40 g, 1.07 mmol) was dissolved in ethanol (20 mL). A solution of lithium hydroxide (0.21 g, 8.57 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 diluted with ethyl acetate. The organic layer was washed with water and brine, dried over magnesium sulfate, filtered, and then concentrated to give the title compound. MS (DCI) m/z 346 (M+H)+.
