✦ Synopsis


Synthesis of tritium labelled BIBN 4096 -1-piperidine-

antagonist for the treatment of migraine is described. Selective tritiation of a heterocyclic aromatic fragment in the presence of aromatic ring in a precursor of BIBN4096 was successfully carried out using the solid state catalytic exchange method. Subsequent completion of the synthesis sequence gave the final [ 3 H]BIBN4096 with a specific activity of >170 Ci/mmol.

The H -antagonists, metiamide and cimetidine were labelled 2 with deuterium and tritium in the 2-position of the imidazole ring by the uncatalyzed exchange reaction with deuterium and tritium oxide at 100°C. The sulfur-35 labelled metiamide was prepared by an exchange reaction with elemental sulfur-
