3.4 g of lithium aluminum hydride was suspended in 100 ml of anhydrous tetrahydrofuran and to the suspension was gradually added 10.0 g of (4-benzylphenoxy)acetonitrile under ice cooling in nitrogen stream. After stirring at room temperature for 1 hour and ice cooling, to the reaction mixture were carefully added 3.4 ml of water, then 3.4 ml of 5N aqueous sodium hydroxide solution and finally 10 ml of water, followed by stirring for a while. Undesired matters were removed by filtration with cerite and the filtrate was concentrated under reduced pressure to obtain 9.8 g of 2-(4-benzylphenoxy)ethylamine. This was used for the subsequent reaction without further purification.
