Reaktionsschritte
A mixture of Example 135C (3.00 g, 5.63 mmol) and 20% sodium hydroxide in water (2.5 mL, 5.63 mmol) in dioxane (35 mL) was heated at 90° C. for 6 hours. The solvent was evaporated. The residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4, and filtered. The filtrate was concentrated to about 10 mL. The solid material was filtered, washed with ethyl acetate and dried to provide the title compound. MS (ESI+) m/z 378 (M+1).
