Reaction Steps

One equivalent of methyl phenylhydrazine (58.76 g; 0.4809 mol, compound 2) was diluted in 50 ml of ethanol and 1.5 ml of acetic acid in a three-necked flask on which was mounted a condenser. The reaction medium was then stirred at 0° C. Using a dropping funnel, 1 equivalent of 4-pyridinecarboxaldehyde (51.5 g; 0.4808 mol, compound 1) was added. After addition of the aldehyde, the reaction medium was heated at 65° C. (oilbath temperature) for 13 hours.
