4-Chloropyridine (3.20 g, 28.2 mmol) and 3,4-dinitrophenol (5.96 g, 32.4 mmol) were combined in an open round-bottom flask fitted with running water condenser. The reaction flask was heated to 145° C. After 45 min, 4N HCl/dioxane (2.1 mL) was added. The reaction was heated for an additional 25 min then cooled to RT. The mix was dissolved in EtOAc and 0.5 N HCl/water. The aqueous layer was basified with 6 N NaOH. A beige solid was isolated and identified as title compound.
