Procedure
To a mixture of tert-butyl 2-(ethylsulfonyl)ethylcarbamate (1.5 g) and ethyl acetate (15 mL) was added dropwise 4N hydrochloric acid•ethyl acetate solution (4 mL) with stirring under ice-cooling. The mixture was stirred at room temperature for 4 hrs., and the precipitated crystals were collected by filtration and washed with ethyl acetate to give 2-(ethylsulfonyl)ethylamine hydrochloride as crystals. (0.76 g, yield 69%). Recrystallization from ethanol gave colorless prism crystals. melting point: 103–104° C.
