실험 절차

Triethylamine (3.46 ml) and 1.82 g of 4-bromobenzoyl chloride were added to a solution of 2.00 g of 6-benzoyloxy-3-cyano-2-hydroxypyridine in 50 ml of dioxane. The mixture was stirred at room temperature for 1 hour. The salt thus produced was separated by filtration and the filtrate was concentrated. The concentrate was applied to silica gel column chromatography using, as an eluent, chloroform, giving 2.97 g of the title compound in a yield of 84%.
