A rapid synthesis of [75Br]-and [77Br] bromperidol with specific activity exceeding 10 000 Ci/mmol is described in which a trimethylstannylated analogue of bromperidol is used as a substrate for regiospecific no-carrier-added radiobromination. 4-[4-[4-(TrimethyLstannyl) phenyl]-4-hydroxypiperidino]-4'-fluorobutyrophenone was synthesized by the reaction of (trimethylstanny1) sodium with haloperidol and purified by preparative HPLC.
