Versuchsvorschrift
A solution of (B) (12 g) in ethanol (200 ml) was neutralized with an ethanolic solution of hydrogen bromide and hydrogenated in the presence of 10% palladium on carbon (2.4 g). After 5 hours the uptake of hydrogen ceased and the catalyst was removed by filtration. The filtrate was taken to dryness in vacuo to give (C) as a semicrystalline solid.
Aufarbeitung
- customthe catalyst was removed by filtration
