In contrast to the commonly used acid hydrolysis of 2-[F-18]fluoro-1,3
,4,6-tetra-O-acetyl-D-glucose to [F-18]FDG, basic hydrolysis is a shor
t, high-yield procedure at room temperature. In case of nucleophilic [
F-18]FDG synthesis the yield of removing the protective groups is quan
titative. Using the electrophilic procedure the yield is about 20% hig
her than in acid hydrolysis. Under optimal conditions (0.3 M NaOH) the
reaction is already completed within 1 min. In alkaline solutions the
formed [F-18]FDG is stable for more than 20 min. Additionally, the fo
rmation of 2-deoxy-2-chloro-D-glucose is avoided.
