الإجراء التجريبي

In tetrahydrofuran, 1-adamantanecarbonyl chloride and 2-bromo-2,2-difluoroethanol were mixed and ice cooled. Triethylamine was added to the mixture. By standard separation operation and solvent distillation, 2-bromo-2,2-difluoroethyl 1-adamantanecarboxylate 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-(1-adamantanecarbonyloxy)-1,1-difluoroethanesulfonate.
