Versuchsvorschrift

In a Fischer-Porter bottle, added a solution of 4-(benzyloxy)-1-(3-fluorobenzyl)pyridin-2(1H)-one (4.5 g, 14.56 mmol) in absolute ethanol-(20 mL). Flushed the solution with nitrogen then added palladium catalyst (1.05 g). Sealed bottle and evacuated system. The system was purged with hydrogen gas (2×15 psi) to check for leaks. The reaction was charged with hydrogen (35 psi) and stirred at room temperature for 45 min. The system was evacuated and flushed with nitrogen. The reaction was filtered and the catalyst was carefully washed with fresh ethanol. The filtrate was concentrated under reduced pressure.
