Procedure

A solution of the product of 1e (5.23 mmol), 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU, 5.23 mmol) and N-methyl-morpholin (5.23 mmol) in 20 mL DMF was stirred at room temperature for 30 minutes. Then (4-aminobutyl)-carbamic acid tert-butyl ester (5.23 mmol) was added and the mixture stirred at room temperature for another 24 hours. The mixture was then diluted with water (100 mL) and the product was isolated through extraction with ethyl acetate.
