实验过程

4 g (0.0212 mol) of the product 2-chloro-3-nitro-6-methoxypyridine, 50 ml of ethanol and 6.32 ml (0.0424 mol) of bis(2-methoxyethyl)amine are placed in a fully equipped round-bottomed flask. The mixture is refluxed for 2 hours with stirring and is then poured onto an ice/water mixture with stirring. The precipitate formed is filtered off by suction and dried under vacuum to constant weight. 5.47 g of yellow powder are obtained, ie a yield of 90.6%.
