Reaction Steps

Iron powder (0.03 g, 0.6 mmol), conc. HCl (0.05 ml), and water (0.5 ml) were added in that order to a solution of 5-isopropyl-2-(4-nitro-1,3-dioxo-2-pentanamido-2,3-dihydro-1H-inden-2-yl)phenyl pentanoate (43 mg, 0.08 mmol) in ethanol (5 ml). The reaction mixture was heated for 1 hrs under reflux. The reaction mixture was hot filtered off, the filtrate was concentrated in a vacuum and purified by column chromatography (ethylacetate:hexane=1:4 to 1:2) to afford the title compound (22 mg, 55%).
