Versuchsvorschrift

10% Palladium on charcoal (550 mg) was added to a solution of 3-[(1-methylethyl)oxy]-N-(5-methylpyrazin-2-yl)-5-[(phenylmethyl)oxy]benzamide (5.5 g, 14.6 mmol) in ethanol (75 mL) and THF (50 mL) and the mixture stirred at RT under a hydrogen atmosphere for 24 hours. The catalyst was removed by filtration and the filtrates evaporated in vacuo to a residue which was crystallised from ethyl acetate to give the desired compound (3.42 g).
