4,5-Dichloropyridin-2(1H)-one is an organic compound that is used in the industrialization of pyridine. It is prepared by refluxing a solution of NaOH and 4,5-dichloro-2-pyridinecarboxaldehyde in a mixture of ethanol and water. The reaction produces dihydropyridine which is then heated to 120 °C with ethylene glycol. The resulting product is crystallized from the mixture and then recrystallized from ethanol.
