Participants

Reaction Steps

5.8 g of the obtained [(4-aminomethylbenzyl)-(4-dipropylaminobutyl)amino]ethyl acetate hydrochloride (14a) was dissolved in 30 ml of water. After the addition of a 1N sodium hydroxide aqueous solution (pH=1), the mixture was extracted twice with 100 ml of chloroform. The chloroform layer was washed with 30 ml of water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure, thereby obtaining 4.45 g of [(4-aminomethylbenzyl)-(4-dipropylaminobutyl)amino]ethyl acetate (14) as a colorless oily substance (yield: 99%, GC: 99.3%).
