실험 절차
In ethyl acetate was dissolved 8.39 g of tert-butyl [(S)-1-(4-dimethylsulfamoylphenyl)-pyrrolidin-3-yl]-carbamate, 200 ml of a solution of 4M hydrochloric acid in ethyl acetate was added thereto, and the mixture was stirred at room temperature for 3 days. The solvent was evaporated, and then, diethyl ether was added to the residue, and the precipitates were collected by filtration to obtain 4-[(S)-3-aminopyrrolidin-1-yl]-N,N-dimethyl-benzenesulfonamide dihydrochloride. To the 4-[(S)-3-aminopyrrolidin-1-yl]-N,N-dimethyl-benzenesulfonamide dihydrochloride were added a saturated aqueous sodium bicarbonate solution and chloroform, the mixture was stirred and the liquids were separated. The organic layer was dried and concentrated under reduced pressure to obtain 5.85 g of 4-[(S)-3-aminopyrrolidin-1-yl]-N,N-dimethyl-benzenesulfonamide.
