실험 절차

Combine 6-chloro-pyridine-3-carbaldehyde (1.00 g, 7.09 mmol), 3-bromo-4-hydroxy-benzonitrile (1.48 g, 7.80 mmol) in dimethylacetamide (40 mL). Add potassium carbonate (1.47 g, 10.64 mmol) and stir and heat the reaction at 130° C. for 2 h. Let cool down the reaction to room temperature and poured into water. Filter the precipitate formed, washing with water, to give the title compound (1.55 g, 72%)
