A mixture of Example 1e (7 g, 18.36 mmol) and lithium hydroxide monohydrate (3.08 g, 73.4 mmol) in tetrahydrofuran (50 mL) and water (20 mL) was heated at 80° C. overnight. After cooling to ambient temperature, the reaction mixture was poured into 300 mL of water. The resulting solid was collected by vacuum filtration to give the title compound (3.92 g, 17.26 mmol, 94% yield).
