Versuchsvorschrift
3-Cyanobenzaldehyde (40.0 mmol) suspended in EtOH (100 mL) was added to a stirred solution of tert-butylcarbazate (40.0 mmol) in EtOH. The mixture was heated at reflux temperature and after 4 h the EtOH was partially evaporated in vacuo. Water (100 mL) was added and the precipitated product was collected by filtration and washed with diethylether to give tert-butyl 2-(3-cyanobenzylidene)-1-hydrazinecarboxylate as a white solid.
