A solution of 3.1 g (0.1 mole) methylamine and 10.1 g (0.1 mole) triethylamine in 100 ml acetonitrile was added dropwise to a solution of 23.4 g (0.1 mole) 1,1,2,2-tetrachloroethylsulfenyl chloride in 200 ml acetonitrile at about 0°-5° C. Into the reaction mixture was then bubbled 9.9 g (0.1 mole) phosgene. The reaction was stirred at about 25° C for about 17 hours. The acetonitrile solvent was evaporated under reduced pressure and the residue was diluted with benzene and filtered to give a filtrate solution of N-1,1,2,2-tetrachloroethylthio N-methyl carbamoyl chloride in benzene.
