Versuchsvorschrift

N-(2-hydroxy-2-(4-isopropyl-2-methoxyphenyl)-5-nitro-1,3-dioxo-2,3-dihydro-1H-inden-4-yl)acetamide (0.10 g, 0.24 mmol) was completely dissolved in anhydrous ethanol (3 ml). This solution was added with iron (0.098 g), conc. HCl (0.05 ml) and water (0.3 ml). The reaction mixture was heated for 2 hrs under reflux. After filtration at high temperature to remove iron, the filtrate was concentrated in a vacuum and purified using column chromatography (ethylacetate 100%) to afford the title compound (90 mg, 98%).
