Abstract
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 [^18^F]fluoride (decay‐corrected yields >60%) efficiently, resulting in an efficient synthesis of 3‐[^18^F]fluoropropyl tertiary amines.
