After potassium carbonate was removed by filtration, 100 ml of water were added, followed by extraction with toluene. The resultant extract was dried over anhydrous sodium sulfate, and then concentrated by an evaporator. Afterward, silica gel column chromatography was done to obtain 2.6 g of the desired amine.
