実験手順

860 mg (0.89 mmol) of the compound from example 19A was dissolved in approx. 20 ml tetrahydrofuran. 620 μl (4.45 mmol) Triethylamine, 168 μl (4.45 mmol) formic acid and 103 mg (0.089 mmol) tetrakis(triphenylphosphin)palladium(0) were added. The reaction mixture was stirred over night at room temperature. The reaction was diluted with approx. 50 ml water and twice extracted with approx. 50 ml dichloromethane. The combined organic phases were extracted with brine, dried over sodium sulfate and concentrated to dryness under reduced pressure. The raw product was purified by preparative RP-HPLC on a C18 column with a water/methanol gradient to yield 329 mg (38% of theory) product.
