实验步骤: A solution of 8.00 g (33.5 mmol) of the compound from Example 51A in toluene (304 ml) was admixed under argon at RT with 10.9 g (50.2 mmol) of the compound from Example 29A in ethanol (100 ml) and 5.10 g (36.8 mmol) of potassium carbonate. After stirring for 10 min, 3.87 g (3.35 mmol) of tetrakis(triphenylphosphine)palladium and then 5.83 g (100 mmol) of potassium fluoride in water (64 ml) were added. The mixture was stirred under reflux for 8 h, and the reaction solution was cooled and diluted with ethyl acetate. The reaction solution was washed in water, and the organic phase was dried over magnesium sulphate, filtered and concentrated under reduced pressure. The residue was purified by means of column chromatography (silica gel, dichloromethane/methanol 100:1→80:1). Yield: 9.20 g (69% of theory, purity 75%) The mixture was stirred under reflux for 8 h the reaction solution was cooled The reaction solution was washed in water the organic phase was dried over magnesium sulphate filtered concentrated under reduced pressure The residue was purified by means of column chromatography (silica gel, dichloromethane/methanol 100:1→80:1)
