摘要

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