The synthesis of 3‐(2‐[ 18 F]fluoroethyl)ethylamino‐6‐diethylaminoacridine ([ 18 F]BF‐108), a potential positron‐labelled probe for imaging amyloid‐β is described. The precursor tosylate derivative was fluorinated with [ 18 F]KF/ Kryptofix 222 in acetonitrile, and the crude product was purified by semi‐preparative HPLC to give the radiolabelled BF‐108. The radiochemical purity was >95% and the maximum specific activity was 33.9 TBq/mmol at the end of the synthesis (EOS). The synthesis time was 130 min from the end of bombardment (EOB).
