실험 절차
500 mg (1.85 mmol) of 3-[(2-methyl-4-oxo-4H-chromen-8-yl)methylene]pentane-2,4-dione are mixed with 349 mg (2.77 mmol) of 2,6-diaminopyrimidin-4-ol, dissolved in 10 ml of isopropanol, and heated under reflux under argon for 2 days. The mixture is filtered and the remaining solid is washed with isopropanol. 660 mg (94% of theory) of the title compound are obtained as a white solid.
