Procedure

To a solution of 4-{3-[(1H-benzimidazol-2-yl)(1-methylpiperidin-4-yloxy)-methyl]phenyl}but-3-ynylamine (50 mg) in methanol (2.5 mL) is added platinum oxide (8 mg). The flask is purged with argon then put under one atmosphere of hydrogen. The reaction mixture is stirred overnight at room temperature then filtered on celite, cake washed with methanol. The solvent is removed under reduced pressure to give 4-{3-[(1H-benzimidazol-2-yl)(1-methylpiperidin-4-yloxy)methyl]phenyl}butylamine.
