Procedure

A solution of 0.7 g (1.54 mmol) of 3-(4-cyanophenyl)-N-{3-[(2,3-dichloro-benzenesulphonyl)methylamino]propyl}propionamide, 3 ml of ethylenediamine and 0.10 g (3.12 mmol) of sulphur was stirred at 100° C. for 15 minutes. Water was then added, and the mixture was extracted with ethyl acetate. The organic extracts were washed with water and saturated sodium chloride solution, dried over sodium sulphate and concentrated. The crude product obtained in this manner was purified by column chromatography on alumina (mobile phase: dichloromethane/methanol 100:1) and then crystallized from ethyl acetate/diethyl ether.
