Procedure

1.9 g (0.01 mol) of the product 2-chloro-3-nitro-6-methoxypyridine, 30 ml of dioxane, 5 ml of water and 2.62 ml (0.02 mol) of 2-butylaminoethanol 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. 1.9 g of yellow powder are obtained, ie a yield of 70%.
