Reaction Conditions

Reaction Steps

Into 75 ml of dry ethyl acetate, were added 7.3 g of anhydrous potassium thiocyanate and 15.7 g of 2,2,2-trichloroethyl chloroformate. The mixture was stirred at 60° C. for 1.5 hours. The reaction mixture was cooled in ice water, followed by an addition of an aqueous ammonia solution (29%) to render the reaction mixture alkaline. The solvent was removed under reduced pressure. The residue was treated with a water/methanol mixed solvent and the reaction product was obtained in a powdery form through filtration. It was then washed thoroughly with water to obtain 14.5 g of 2,2,2-trichloroethyl N-thiocarbamoylcarbamate.
