Versuchsvorschrift

The product from Example 59A (0.061 g, 0.212 mmol), the product from Example 60E (0.08 g, 0.212 mmol), tris(dibenzylideneacetone)dipalladium(0) (5.8 mg, 6.35 μmol), 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamante (6.2 mg, 0.021 mmol) and potassium phosphate (0.157 g, 0.74 mmol) were combined and sparged with argon for 15 minutes. Meanwhile a solution of 4:1 dioxane/water (2 mL) was sparged with nitrogen for 15 minutes and transferred by syringe into the reaction vessel under argon. The mixture was stirred at 60° C. for 2 hours and partitioned between ethyl acetate and water. The organic layer was washed with saturated aqueous sodium chloride, dried (anhydrous Na2SO4), treated with 3-mercaptopropyl functionalized silica gel, filtered, and concentrated to afford the title compound (0.1 g, 100%).
