Donepezil (1-benzyl-4-[(5,6-dimethoxy-1-oxoindan-2-yl)methyl-]piperidine), a potent acetylcholine esterase inhibitor, was labelled with [C-11]iodomethane by O-methylation of the O-6'-desmethyl precursor. Synthesis, purification and formulation were performed in approximately 30 min with an average specific activity of 39.5 GBq/mu mol at EOS. The total activity available for applications was 7.5-11.1 GBq.
