Radiosynthesis of 18F fluorthanatrace (18F-FTT). Radiofluorination was carried out with tosylate precursor. After the drying of 18F F−, the reaction was carried out at 100°C for 10 minutes, followed by semipreparative high-performance liquid chromatography purification. The process was developed on automated synthesis module for clinical studies. The overall reaction time is around 60 minutes with yield between 20% and 50%. — Radiosynthesis of ¹⁸F fluorthanatrace (¹⁸F-FTT). Radiofluorination was carried out with tosylate precursor.
