Reaction Steps
Pivalic acid chloride and 2-bromo-2,2-difluoroethanol were mixed in tetrahydrofuran and ice cooled. Triethylamine was added to the mixture. By standard separation operation and solvent distillation, 2-bromo-2,2-difluoroethyl pivalate was obtained. This compound was converted into a sodium sulfinate with sodium dithionite and then oxidized with hydrogen peroxide, yielding the target compound, sodium 2-(pivaloyloxy)-1,1-difluoroethanesulfonate.
