실험 절차

Under a nitrogen atmosphere, a solution of tert-butyl N-(4-aminobutyl)carbamate (13.8 g, 73.4 mmol) and triethylamine (15.3 mL, 110 mmol) was cooled to 0° C. Methanesulfonyl chloride (6.3 mL, 81 mmol) was added, and the reaction was allowed to warm to ambient temperature and stirred overnight. Aqueous acetic acid (200 mL of 10%) was added. The organic layer was then separated and washed with water (200 mL), saturated aqueous sodium bicarbonate (200 mL), water (200 mL), and brine; dried over sodium sulfate; filtered; and concentrated under reduced pressure to provide 18.9 g of tert-butyl [4-(methanesulfonylamino)butyl]carbamate as an off-white solid.
