97 ± 9.06 nM), low lipophilicity and good metabolic stability. ‘Click’ labeling afforded [18F]16 in 37.0 ± 3.6% decay corrected radiochemical yield based on azide [18F]14 and 7% end of synthesis (EOS) yield from aqueous fluoride. Compound [18F]16 was obtained with >99% radiochemical purity in a total synthesis time of 3 h. The compound showed good stability in vivo and a fourfold higher uptake in high
