실험 절차

A solution of hydrochloric acid in ethanol was added to a solution of tert-butyl [4-(methanesulfonylamino)butyl]carbamate (18.9 g, 71.1 mmol) in ethanol (100 mL), and the reaction was heated at 100° C. for two hours. The solvent was removed under reduced pressure. A mixture of dichloromethane:hexanes was added to the resulting oil and removed under reduced pressure; this process was repeated several times. The residue was dried for three days under vacuum to provide 14.3 g of N-(4-aminobutyl)methanesulfonamide hydrochloride as a tan solid.
