実験手順
A solution of 4-(2-amino-2-methylpropyl)aniline hydrochloride salt (1.0 g, 4.98 mmol) in anhydrous DMF (30 mL) was treated with benzenesulfonyl chloride (880 mg, 4.98 mmol). The solution was stirred at ambient temperature for 16 h. The solvent was removed under reduced pressure and the residue was washed twice with hexane. The insoluble material was dissolved in water and extracted twice with ethyl ether to remove any remaining neutral impurities. The aqueous layer was separated and basified with excess 1N sodium hydroxide. Upon standing, a crystalline solid soon precipitated. The solid was collected, and dried under vacuum at 60° C. to provide 570 mg (38%) of the desired product as a white crystalline solid. Mp 180–181° C.
