実験手順
A solution of 2-fluoro-6-iodobenzonitrile (17.82 g, 72.15 mmol) and azidotrimethyltin (15.00 g, 72.88 mmol) in 150 mL toluene was heated to 125° C. for 72 hours. The solution was cooled to room temperature and partitioned between ethyl acetate and 0.5 N HCl. The organic extract was washed with water and brine, dried over Na2SO4, filtered and concentrated under vacuum to provide 5-(2-fluoro-6-iodo-phenyl)-1H-tetrazole that gave proton NMR spectra consistent with theory and a mass ion (ES+) of 291.01 for M+H+.
