Versuchsvorschrift

A mixture of N-[1-(4-chlorophenyl)-1-methylethyl]acrylamide (200 g), imidazole (60.9 g), Triton B (20 ml) and 1,4-dioxane (1600 ml) was stirred and boiled under reflux for 20 hours. The solvent was removed under reduced pressure and the residue dissolved in dichloromethane (2000 ml). The mixture was extracted with 2M hydrochloric acid. The combined aqueous extracts were basified with 2M sodium hydroxide solution and extracted with dichloromethane to give N-[1-(4-chlorophenyl)-1-methylethyl]-3-(imidazol-1-yl)propionamide, m.p. 154°-155° C.
