Versuchsvorschrift

Seven grams of 3-carbethoxythiomorpholine and 6.5 g of 4-chlorophenyl isocyanate were added to 60 ml of hexanes containing 10 drops of triethylamine as a catalyst. A mild exothermic reaction took place as the reactants mixed. After the mixture cooled to room temperature, the precipitate was collected by filtration and recrystallized from a mixture of methylene chloride and ether to give 4 g of 3-carbethoxy-4-(4-chlorophenylaminocarbonyl)thiomorpholine, mp 152.5°-154.5° C.
