실험 절차

The product from Example 311e (0.075 g, 0.198 mmol), the product from Example 6a (0.085 g, 0.198 mmol), tris(dibenzylideneacetone)dipalladium(0) (5.45 mg, 5.95 μmol), 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamante (5.80 mg, 0.020 mmol) and potassium phosphate (0.126 g, 0.595 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 for 2 hours at 60° C. and partitioned between ethyl acetate and water. The organic layer was washed with saturated aqueous sodium chloride, dried (Na2SO4), treated with 3-mercaptopropyl functionalized silica gel, filtered, and concentrated. Purification by trituration in dichloromethane afforded the title compound (0.083 g, 70%).
