Procedure

N-methyl-N-glycidyl-perfluorooctanesulfonamide ("epoxide A") was prepared by placing 450 grams N-methyl-perfluorooctanesulfonamide ("amide A") in a two-liter three-necked round-bottom flask and heating to 80° C., 101 grams epichlorohydrin was then added followed by 91 grams methanol. The temperature was reduced to 65° C. before 30 grams 25 wt % sodium methoxide in methanol solution was slowly added keeping the temperature below 70° C. 60 grams 50 wt % aqueous sodium hydroxide solution was slowly added keeping the temperature below 70° C. After addition the reaction was stirred at 65° C. overnight. Water-aspirator vacuum was applied to the flask and excess methanol and epichlorohydrin were removed. 450 grams water was then added to the flask with stirring at 65° to wash the product. The water was decanted after allowing the product to settle. This washing step was repeated a second time. Vacuum was applied to 20 mm Hg and the temperature of the flask was raised to 90° C. to remove volatile materials.
