(1) was brominated, chlorinated, and iodinated using molecular bromine in acetic acid or N-halosuccinimides in trifluoroacetic acid. Initial halogenation occurs at C-3, followed (in the cases of chlorine and bromine) by the less reactive C-8, to afford 3-haloboldines- and 3,8-dihaloboldines (2-5). Using a 2:1 ratio of N-iodosuccinimide to boldine, however, only the 3-iodo derivative 6 was obtained. Radioligand
