Versuchsvorschrift
40 g (0.21 mol) of 5-acetyl-2-chloro-3-cyano-6-methyl-pyridine are dissolved in 800 ml of tetrahydrofuran, 200 ml of concentrated aqueous NH3 solution are added, and the mixture is heated at 80° C. in a stirred autoclave for two hours. After cooling, the mixture is concentrated and filtered, and the filter cake is extracted by boiling in acetonitrile and is filtered with suction.
