This study describes the synthesis of a fluoroethylated derivative of [N-methyl-11C]2-(4′-methylaminophenyl)-6-hydroxybenzothiazole ([11C]6-OH-BTA-1; Pittsburgh Compound B (PIB)), an already established amyloid imaging agent. The [11C]methylamino group of [11C]6-OH-BTA-1 was formally replaced by a fluoroethyl group in a cold synthesis via N-alkylation of N-Boc-2-(4′-aminophenyl)-6-(methoxyethoxymethoxy)benzothiazole with fluoroethyl tosylate. Subsequent deprotection gave the target compound 2… CONTINUE READING
