The reaction mixture is stirred for 1/2 hour at 25° C and 11/2 hour under reflux. 83.5 parts of phosphorus pentachloride are then added and the mixture is stirred for 4 hours under reflux (83° C) until the evolution of gas has ceased. On concentrating under reduced pressure, and distilling, 84 parts (58% of theory) of N-ethyl-N-chloromethylsulfamic acid chloride of boiling point 70°-75° C/0.1 mbar and nD25 = 1.4800 are obtained.
