In a search for high-affinity receptor ligands that might serve for development as radioligands for the imaging of brain 5-HT4 receptors in vivo with positronemissiontomography (PET), structural modifications were made to the high-affinity 5-HT4 antagonist (1-butylpiperidin-4-yl)methyl 8-amino-7-iodo-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylate (1, SB 207710). These modifications were made mainly
