Reaction Steps

To a solution of Example 3D (2.6 g, 4.60 mmol) in dioxane was added 6M sodium hydroxide (7.67 mL, 46 mmol). The mixture was stirred at 100° C. for 2 hours, cooled and diluted with 50 mL ethyl acetate. The organic layer was washed with saturated sodium bicarbonate solution, water and brine, dried over magnesium sulfate, filtered, and concentrated to give the title compound, which was used without further purification.
