Abstract

5-(2-Phenylethynyl)pyridine-3-[11C]carbonitrile ([ 11C]LY2232645), a metabotropic glutamate 5 receptor (mGluR5) antagonist, was synthesized by a no-carrier-added nucleophilic halogen displacement with [11C]copper(I) cyanide. The average radiochemical yield was 2.5%, and the average specific activity was 1365 mCi/μmol at end-of-synthesis. The total time of synthesis, purification, and formulation was 26 min.
