Versuchsvorschrift

tert-Butyl 2-(3-cyanobenzylidene)-1-hydrazinecarboxylate (60.0 mmol) was dissolved in MeOH (250 mL) and 10% Pd/C (10 w/w %) was added. The mixture was hydrogenated for 6 h. The catalyst was filtered off and the filtrate was evaporated in vacuo to yield oily tert-butyl 2-(3-cyanobenzyl)-1-hydrazinecarboxylate which crystallized overnight.
