4 g (0.0212 mol) of the product 2-chloro-3-nitro-6-methoxypyridine, 40 ml of ethanol and 3.86 g (0.042 mol) of 2-aminopropane-1,3-diol 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. 4.54 g of yellow powder are obtained, ie a yield of 88.2%.
