LAH (570 mg, 0.015 mol, 1.5 eq) was dissolved in THF (30 ml), and to this solution was added dropwise a THF solution (50 ml) of 3-(4-benzyloxyphenyl)-propionitrile (2.37 g, 0.01 mol, 1.0 eq) under ice-cooling. After the completion of the dropwise addition, the mixture was stirred at room temperature for 2 hours. This reaction mixture was cooled with ice-cold water, and a saturated aqueous sodium sulfate solution (about 30-40 ml) was added. After filtration through Celite, the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (chloroform/metanol=10/1-5/1) to give 3-(4-benzyloxyphenyl)propylamine (1.2 g, 49.7%) as a pale-yellow amorphous compound.
