Procedure

10% Palladium-carbon (catalytic amount) was added to a methanol (15 ml)/water (5 ml) solution containing 4-[(E)-2-piperidin-4-ylvinyl]benzamide hydrochloride (800 mg), followed by stirring in a hydrogen gas atmosphere at room temperature under normal pressure for 4 hours. The catalyst was removed by filtration, and the resulting filtrate was concentrated under reduced pressure. The resulting solid was recrystallized from ethanol/acetonitrile to obtain 4-(2-piperidin-4-ylethyl)benzamide hydrochloride (451 mg) (Reference Example 58).
