The synthesis of the first permanently charged melatonin receptor ligand: N-[2-(2-trimethylammoniumethyleneoxy-7-methoxynaphthyl)ethyl]propionamide iodide (2a, TMEPI) and its carbon-14 analog (2b, C-14-TMEPI) are described. The ligands can serve as tools to elucidate the mechanism of melatonin receptor regulation. Both compounds 2a and 2b are synthesized in 8 steps. The radiochemical yield and purity of 2b are 99.6 and 99.8% respectively, with specific radioactivity of 7.6 mCi/mmol.
