Versuchsvorschrift

80 mg (0.22 mmol) of the compound from example 68 were initially charged in methanol (4 ml), then 12 mg (0.045 mmol) of platinum(IV) oxide were added and the reaction mixture was hydrogenated at standard pressure overnight. The reaction mixture was filtered through Celite and the filtercake was washed with methanol. The filtrate was concentrated to give 79 mg (92% purity, 90% of theory) of the title compound, which were converted without further purification.
