Versuchsvorschrift

A mixture of 340 mg (0.71 mmol) of the product of Example 203 and 35 mg of 10% palladium on carbon in 15 ml of ethanol was hydrogenated on a Parr shaker for 2 hr. The resulting mixture was filtered through Celite and Magnesol to provide 325 mg (95%) of the desired product as a colorless gum. Electrospray Mass Spec 478(M+H).

Aufarbeitung
