| Product | 1-(4-Pyridyl)-4-piperidone Hydrazone | HCID 22727202 | — |
Reaction Steps
A solution of 1-(4-pyridyl)-4-piperidone (3.52 g) and hydrazine hydrate (1.25 q) in ethanol (50 ml) was stirred at room temperature for 15 hours. The reaction mixture was concentrated and the residue obtained was crystallized from ether to obtain [1-(4-pyridyl)-4-piperidinylidene]hydrazine (3.51 g) as colorless crystals.
