Versuchsvorschrift

A solution of 0.5 g (2.04 mmol) of 2,3-dichlorobenzenesulphonyl chloride, 0.26 g (2.04 mmol) of 1-(2-aminoethyl)-2-imidazolidone and 1 ml (7.18 mmol) of triethylamine in 10 ml of tetrahydrofuran was stirred at room temperature overnight. The reaction mixture was then washed with 1 N HCl and saturated sodium bicarbonate solution, dried over sodium sulphate and concentrated. The product obtained in this manner was reacted further without additional purification.
