In 15 ml of ethanol was dissolved 0.215 g of 3-amino-4,5-diethoxycarbonyl-2-phenyl-6-(1,2,4-triazol-1-yl)pyridine, whereto 1 ml of hydrazine monohydrate was added. The mixture was heated under reflux for 7 hours. After cooling, the resulting yellow crystals were collected by filtration and washed with ethanol.
