Versuchsvorschrift

A solution of intermediate 9 (5.88 g, 22.44 mmol) in ethanol (200 ml) was hydrogenated at room temperature in the presence of palladium 10% on activated carbon (0.58 g) for 3 hours. The solids were filtered off and the filtrate was evaporated till dryness to yield intermediate 10 (5.20 g, >99%) that was used without further purification.

Aufarbeitung

  1. filtrationThe solids were filtered off
