Methyl 4-(pyridine-3-yloxy)benzoate (4.8 g, 20.94 mmol) was dissolved in ca. 150 mL of EtOH and anhydrous hydrazine (4.08 g, 4.0 mL) was added via a syringe. The resulting yellow solution was refluxed for 24 hrs. Then solvent was removed in vacuo to give the title product (4.8 g, 100% yield) as yellow viscous oil, which upon standing slowly solidified.
