実験手順
N-(2,2-dihydroxy-5-nitro-1,3-dioxo-2,3-dihydro-1H-inden-4-yl)acetamide (2.60 g, 11.1 mmol) was completely dissolved in anhydrous dioxane (20 ml). This solution was added with selenium oxide (2.70 g, 24.4 mmol) and AcOH (1.5 ml). The reaction mixture was heated for 7 hrs under reflux. After filtration at high temperature, the filtrate was concentrated to afford 1.79 g (100%). Trifluoroacetic solution of the resulting product was added with isopropyl-3-methoxybenzene (1.66 g, 11.1 mmol), followed by stirring for 12 hrs. The remainder was extracted with ethyl acetate, and concentrated organic layer was purified using column chromatography (ethylacetate 100%) to afford the title compound (0.64 g, 14%).
