摘要：
The new **1**8F-labelled precursor 1- left bracket **1**8F right bracket fluoro-2-pyridone was prepared by reacting left bracket **1**8F right bracket F//2 with 2-(trimethylsiloxy)pyridine. This compound has potential as an easy to use yet selective labelling reagent in preparations, where fluorine carrier may be tolerated. Pure ( greater than 92 percent) 1- left bracket **1**8F right bracket fluoro-2-pyridone is obtained within 35 min from end of bombardment in yields of up to 48 percent. Quality control consisted of HPLC combined with **1**9F-NMR spectroscopy. The mean specific activity of several preparations was 4MBq/ mu mol ( epsilon equals 16. 6). The precursor may be used directly or purified by sublimation.
