الإجراء التجريبي

4 g (0.0219 mol) of the product 2-chloro-3-nitro-6-methoxypyridine, 50 ml of ethanol and 4.15 ml (0.0438 mol) of 3-methylamino-1,2-dihydroxypropane 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. 4.74 g of yellow powder are obtained, ie a yield of 87.1%.
