Reaction Steps

To a solution of 2-[(1-methylpiperidin-4-yloxy)(4-nitrophenyl)methyl]-1H-benzimidazole (example 447, 200 mg) in methanol (5 mL) and a solution of 5N hydrochloric acid in isopropanol (0.2 mL) is added 10% palladium on carbon (50 mg). The flask is evacuated and filled with hydrogen (balloon) and stirred overnight at room temperature. The reaction mixture is filtered on celite and the solvents are evaporated under reduced pressure to dryness. The residual solid is triturated twice with diethyl ether and the solid is filtered and dry to afford 4-[(1H-benzimidazol-2-yl)(1-methylpiperidin-4-yloxy)methyl]aniline hydrochloride as a cream-colored solid melting at 185° C.
