実験手順
309 mg (1.07 mmol) of 4-[(4-dipropylaminobutyl)amino]methylbenzonitrile (2a) was added dropwise in a 100 ml recovery flask, and dissolved in 9.2 ml of anhydrous methanol. 0.134 ml of a formaldehyde aqueous solution (35%) was then added to the solution. 201.7 mg of sodium cyanoborohydride was then added to the mixture. After the addition of acetic acid to adjust the mixture to pH 5.0, the mixture was stirred at room temperature for 24 hours. 1 mol/l sodium hydroxide aqueous solution was then added to the mixture, followed by extraction with chloroform. The extract was dried over magnesium sulfate and concentrated, thereby obtaining 296.2 mg of 4-[(4-dipropylaminobutyl)methylamino]methylbenzonitrile (2b) was obtained as a colorless oily substance (yield: 92%).
