2,6-Dimethoxypyridine Use and Manufacturing

(1) In a 500 ml reaction flask, 29.6 g was added2, 6-dichloropyridine, 16 g of solid sodium hydroxide and 200 ml of methanol, Stirring began to heat up to reflux, the reaction time was 8 hours, Stop the reaction, steamed most of the methanol, cooled, add 100 ml of water, Extract once with dichloromethane, remove methylene chloride to give the crude product, The crude product was distilled under reduced pressure to give 2, 6-dimethoxypyridine in 94percent yield.
