Versuchsvorschrift

A suspension of Example 149d (88.0 mg, 0.203 mmol) in ethanol (2 mL) was treated with a solution of potassium hydroxide (45.5 mg, 0.811 mmol) in water (0.5 mL). The reaction mixture was heated at 50° C. for 1.5 hours. After concentration, water was added to the residue and the mixture was sonicated. The solid was filtered, washed with water, and oven-dried to give 51.3 mg of the title compound.
