Procedure
Palladium on activated carbon (moistened with about 50% water, 0.3 g/mmol) was added to a solution of 500 mg (1.88 mmol) of 5-[4-(trifluoromethyl)phenyl]pyridine-3-carboxamide (Example 50A) in 60 ml of acetic acid, and the mixture was hydrogenated in a 60 bar hydrogen atmosphere at 85° C. overnight. The catalyst was then filtered off through a filter layer and washed repeatedly with ethanol. The combined filtrates were concentrated under reduced pressure. This gave 0.61 g (98% of theory) of the target compound, which was reacted without any further purification steps.
