Setoperone (INN Tooltip International Nonproprietary Name; USAN Tooltip United States Adopted Name; developmental code name R-52245) is a compound that is a ligand to the 5-HT2A receptor. [1] It can be radiolabeled with the radioisotope fluorine-18 and used as a radioligand with positron emission tomography (PET). Several research studies have used the radiolabeled setoperone in neuroimaging for the studying neuropsychiatric disorders, such as depression [2] or schizophrenia. [3] The drug was first described by at least 1984. [1]

Synthesis

Synthesis: Radiolabelled:

The starting material is called 6-(2-hydroxyethyl)-7-methyl-2,3-dihydro-[1,3]thiazolo[3,2-a]pyrimidin-5-one, CID:15586462 (1). Halogenation of this with hydrobromic acid in acetic acid gives CID:15586463 (2). Sn2 alkylation with 4-(4-fluorobenzoyl)piperidine [56346-57-7] (3) under Finkelstein reaction conditions affords setoperone (4).
