Reaction Steps

A solution of 2-[1-(3-methoxybenzoyl)piperidin-4-yl]ethylamine (4.5 g) in tetrahydrofuran (40 ml) was added dropwise to a suspension of lithium aluminum hydride (1.63 g) in tetrahydrofuran (50 ml) under refluxing. After 30 minutes, the mixture was cooled to 0° C., and ethyl acetate (5 ml), water (2 ml), 4N sodium hydroxide (4 ml), water (2 ml) and magnesium sulfate were added thereto successively. The resulting precipitates were removed out by filtration and the filtrate was evaporated in vacuo. The residue was chromagographed on alumina eluting with 2% methanol in chloroform to give 2-[1-(3-methoxybenzyl)piperidin-4-yl]ethylamine (1.8 g) as an oil.
