Versuchsvorschrift

12.4 g. N-2-chlorophenyl-N-propyl(thiocarbamoyl) chloride and 6.8 g. imidazole were refluxed in 75 ml. dry tetrahydrofuran for 16 hours. A further 2 g. imidazole was then added and the heating continued for 8 hours. After separating the solid formed evaporation of the tetrahydrofuran left an oil which was dissolved in methylene chloride. The resulting organic phase was washed with water, dried with soldium sulphate and the solvent evaporated to leave an oil which crystallised on treatment with light petroleum and chilling to give the product, 1-[N-2-chlorophenyl-N-propyl (thiocarbamoyl)]imidazole, m.p. 59°-61° C.
