Reaction Steps

2-fluoro-8-((5-iodo-2,3-dihydrobenzofuran-6-yl)methyl)-9H-purin-6-amine (S16-9). To a suspension of S16-8 (0.45 g, 1.6 mmol) in 50 mL acetonitrile was added 1 mL of TFA. To the resulting solution was added NIS (1.06 g, 4.7 mmol) and the reaction mixture was stirred at rt for 3 h. It was then evaporated to dryness and purified by flash chromatography to give S16-9 (0.408 g, 63%) as a yellow solid. 1H NMR (500 MHz, MeOH-d4) δ 7.67 (s, 1H), 6.76 (s, 1H), 4.59 (m, 2H), 4.28 (s, 2H), 3.21 (m, 2H); MS: m/z 412 (M+H)+.
