Versuchsvorschrift

To a solution of 10.0 g (50 mmol) of 4-bromophenethylamine and 7.6 mL (55 mmol) of triethylamine in 150 mL of dichloromethane was added a solution of 6.2 mL (55 mmol) of isopropylsulfonyl chloride in 40 mL of dichloromethane dropwise. The mixture was stirred at room temperature for 18 h. The mixture was washed with 100 mL of 1N aqueous hydrochloric acid, the organic layer was separated and the aqueous layer extracted one time with 100 mL each of dichloromethane. The combined organics were dried (Na2SO4), filtered and concentrated in vacuo to afford 6.7 g (44%) of the title compound.
