A rapid and efficient protocol to afford the title compound 2-[18F]-fluoro-2,2-difluoroethyl tosylate ([18F]7b) is described. Starting from [18F]fluoride ion, labelling reagent 7b was obtained in good yields and a high specific radioactivity. Compound ([18F]7b) was then used to synthesise a prospective radiotracer for PET-imaging in dementia.
