Versuchsvorschrift
2 g (11.57 mmol) of 1-(6-chloropyrid-3-yl)ethanone and 70 mL of ammonium hydroxide are placed in a Parr reactor. The solution is heated at 130° C. overnight. The mixture obtained is evaporated to dryness, and the residue is taken up in ethyl acetate and washed with water and with saturated NaCl solution. The organic phase is dried over sodium sulfate and evaporated to dryness to give 1.14 g of 1-(6-aminopyrid-3-yl)ethanone, the characteristics of which are as follows:
