実験手順
3.57 g of methylamine is condensed in a solution of 1.8 ml of (3-bromo-propoxymethyl)-benzene in 15 ml of anhydrous tetrahydrofuran at −78° C., and it is stirred overnight at room temperature in a pressurized reactor. After the pressurized reactor was opened at −20° C., it is allowed to come to room temperature to allow excess methylamine to evaporate off. Then, the reaction solution is added to saturated sodium chloride solution, extracted with ether, dried on magnesium sulfate and concentrated by evaporation in a vacuum. 1.91 g of (3-benzyloxy-propyl)-methyl-amine is obtained as a crude product, which is used without further purification in the next stage.
