Procedure

In pyridine (30 ml), 378 mg (0.949 mmol) of the compound from Example 7A were introduced and then 143 mg (0.135 mmol) of palladium (10% on carbon) were added. The mixture was hydrogenated overnight at RT under standard hydrogen pressure. The suspension was then filtered through kieselguhr and the filtercake was washed with ethanol. The filtrate was concentrated and yielded 233 mg (81% purity, 51% of theory) of the desired compound, which was reacted without further purification.

Workup

  1. filtrationThe suspension was then filtered through kieselguhr
  2. washthe filtercake was washed with ethanol
  3. concentrationThe filtrate was concentrated
