Sodium Iodide → [(Methylsulfanyl)methoxy]benzene

Temperature

0 °C

N—BOC protected compound 22 (0.202 g 0.434 mmol) was dissolved in 2.0 mL of dry THF under argon and cooled to 0° C. Sodium hydride (0.018 g of a 60% dispersion, 0.46 mmol) was added and the reaction continued to stir at 0° C. for fifteen minutes. Sodium iodide (0.071 g 0.48 mmol), hexamethylphosphoramide (0.45 mL, 2.6 mmol), and chloromethylthiomethyl ether (36 μL, 0.48 mmol) were added in that order. After stirring for five minutes, the ice bath was removed and the reaction was warmed to room temperature. After stirring for another 45 minutes, water was added to the reaction mixture and it was extracted with ethyl acetate. The organics were combined and dried over sodium sulfate. Purification was accomplished using column chromatography eluting with 6:1 hexanes/ethyl acetate to provide methlythiomethylphenyl ether 23 (0.203 g 89%) as an oil, 1H-NMR (300 MHz, CDCl3) δ 7.07 (m, 2H), 6.86 (d, J=8.5 Hz, 2H), 5.11 (s, 2H), 4.84 (m, 1H), 4.33 (m, 1H), 3.91 (m, 1H), 3.35 (m, 3H), 2.83 (m, 1H), 2.24 (s, 3H), 2.06 (s, 3H), 1.48 (s, 9H), 0.81 (s, 9H), −0.02 (s, 6H).
