Versuchsvorschrift

1-[2,4-Dihydroxy-3-(2-propenyl)benzoyl]pyrrolidine (260 mg, 1.05 mmol), the compound of Example 23 (440 mg, 1.05 mmol), and potassium carbonate (350 mg, 2.4 mmol) were added to about 15 to 20 ml of DMF, and the reaction mixture was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate and washed with water. The organic layer was dried over magnesium sulfate and concentrated under vacuum. Chromatography of the crude material on silica gel using 20% ethyl acetate/hexane as eluant gave the product.
