Abstract

An improved synthesis of 3-{2-[2-(bromomethyl)thia­zol-4-yl]ethynyl}-5-fluorobenzonitrile, a precursor for PET radioligand [¹8F]SP203, is described, wherein a new synthon was employed for Sonogashira coupling with 3-bromo-5-fluorobenzonitrile. The new five-step synthesis provided the title compound in 56% overall yield starting from 4-bromo-2-formylthiazole.
