Versuchsvorschrift

A mixture of 23.5 g. of N-(4-chloro-2-butenyl)-isoindole-1,3(2H)-dione, 11.0 g. of sodium imidazol and 200 ml. of dimethyl formamide was heated on the steam bath for 18 hours and concentrated to remove the solvent; the residue was taken up in methylene chloride, washed with water, dried with magnesium sulfate and again concentrated. The residue was dissolved in hot ethylacetate and allowed to cool and N-[4-(1H-imidazol-1-yl)-2-butenyl]isoindole-1,3-(2H)-dione, m.p. 106°-108° C., was obtained.
