Reaction Steps
The propanone was dissolved in 1 L of ethanol, 5.8 mL (0.12 mol) of hydrazine hydrate was added, and the mixture was heated to reflux for 1 hr. The ethanol was stripped off in vacuo, and the residue was put through a 600 g silica gel column eluting with 1:1 hexane-acetone to yield about 4 g of 4,5-bis(2-pyridinyl)-1H-pyrazole as a light tan solid after removal of solvent.
