Reaktionsschritte

A mixture of the triflate from Step 6 of Example 1 (3.98 g, 10 mmol), trioctylsilane (6.7 mL, 15 mmol), triethyl amine (7.0 mL, 25 mmol), palladium acetate (0.22 g, 0.5 mmol) and diphenylphosphine (0.21 g, 0.5 mmol) in DMF (60 mL) was stirred at 80° C. under an atmosphere of carbon monoxide (50 psi) for 5 h. The reaction was then diluted with ethyl acetate and water. The organic layer was washed with water and concentrated. The residue was purified by chromatography on silica gel to give the title product.
