3beta-(4-Iodophenyl)nortropane-2beta-carboxylic acid methyl ester (I) was alkylated with 1-bromo-3-fluoropropane (II) in triethylamine to give the N-fluoropropyl derivative (III). Stannylation of the iodophenyl ring of (III) by Pd(0)-catalyzed reaction with hexamethylditin afforded the corresponding 4-(trimethylstannyl)phenyl tropane (IV). The 123I-labeled compound was then prepared by iododestannylation of (IV) with Na[123I] in the presence of peracetic acid.
