3-Methanesulfonyloxypropyl tertiary amines were observed to cyclize to form azetidinium methanesulfonate moieties. Heat-induced cyclization of 3-methanesulfonyloxypropyl amines was utilized for preparation of azetidinium methanesulfonates. The azetidinium methanesulfonates were found to incorporate radioactive [18F]fluoride (decay-corrected yields >60%) efficiently, resulting in an efficient synthesis of 3-[18F]fluoropropyl tertiary amines.
