Versuchsvorschrift

32 g (0.09 mol) of di-tert-butyl 1-(1-acetylpiperidin-4-yl)hydrazine-1,2-dicarboxylate were dissolved in 300 mL of methanol and 30 mL of HCl 4 M in dioxane were added. The mixture was stirred at room temperature overnight. The solvent was then evaporated and the residue crystallized from ethanol, giving 14 g (77% yield) of the title compound.
