Methyl iodide → 3-(Methoxymethyl)pyridine

Participants

Reaction Steps

To a mixture of 10.0 g of 3-hydroxymethylpyridine and 200 ml of THF, 3.7 g of 60% sodium hydride (in oil) was added in small portions at room temperature and then stirred for 15 minutes. To the reaction mixture, 13.0 g of methyl iodide was added dropwise, and the reaction mixture was stirred at room temperature for three hours. To the reaction mixture, 25 ml of water was added. Then, the reaction mixture was concentrated under reduced pressure. To the residue, 25 ml of water was added, followed by extraction with ethyl acetate three times. The combined organic layers were washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 8.17 g of 3-methoxymethylpyridine.
