Versuchsvorschrift

92 g (0.239 mol) of trans-1-benzoyl-3-bromo-4-(2-hydroxyethoxy)-pyrrolidine, 32 g (0.316 mol) of triethylamine and 1 g of 4-dimethylaminopyridine are dissolved in 750 ml of toluene, and 60 g (0.31 mol) of tosyl chloride in 450 ml of toluene are added dropwise. The mixture is stirred for two days at room temperature, water is added, and the aqueous phase is separated off and extracted with toluene. The toluene solutions are washed with 10% hydrochloric acid, dried over magnesium sulphate, concentrated, dissolved in ethyl acetate and filtered through silica gel. The filtrate is concentrated.
