Vorschrift

1-adamantanecarbonyl chloride and 2-bromo-2,2-difluoroethanol were mixed in tetrahydrofuran, and ice-cooled. Triethylamine was added into the mixture, and then a typical liquid separating operation and a distillation removal of solvent were conducted, to obtain 1-adamantanecarboxylic acid=2-bromo-2,2-difluoroethyl. Next, conversion into sodium sulfinate by sodium dithionite and oxidation by hydrogen peroxide were conducted for the mixture, to obtain intended sodium 2-(1-adamantanecarbonyloxy)-1,1-difluoroethanesulfonate.
