Versuchsvorschrift

A solution of 4.0 g of 2-chloro-4-isopropylsulphonyl-(3,4-dinitrophenoxy)benzene and 3.85 g of 3-aminopropionitrile. 0.5 fumarate in 100 ml of acetonitrile, to which 4.1 g of potassium carbonate was added, was refluxed for 6 hours. After evaporation the residue was dissolved in methylenechloride an extracted with water. After washing with water the organic layer was filtered and reduced. Recrystallisation from methanol yielded 3.0 g of the desired product; m.p. 140° C.
