Versuchsvorschrift

N-(2,2-dihydroxy-7-nitro-1,3-dioxo-2,3-dihydro-1H-inden-4-yl)acetamide (1.50 g, 6.4 mmol) was completely dissolved in anhydrous dioxane (15 ml). This solution was added with selenium oxide (1.56 g, 14.0 mmol) and AcOH (1.5 ml). The reaction mixture was heated for 12 hrs under reflux. After filtration at high temperature, the filtrate was concentrated to afford 1.79 g (100%). A trifluoroacetic acid solution of the resulting product was added with isopropyl-3-methoxy benzene (962 mg, 6.4 mmol) followed by stirring for 12 hours. The resulting product was extracted with ethyl acetate, and concentrated organic layer was purified using column chromatography (ethylacetate:hexane=1:1) to afford the title compound (0.52 g, 20%).
