To a mixture of 3-((6-nitro-1H-indol-1-yl)methoxy)benzonitrile (3.0 g, 10.2 mmol), THF (80 mL) and water (40 mL) were added iron powder (2.86 g, 51.2 mmol) and NH4Cl (1.09 g, 20.4 mmol) and the mixture was stirred at 64° C. overnight. The mixture was then cooled to rt and to the resulting mixture was added saturated NaHCO3 aqueous solution. The mixture was filtered and the filtrate was extracted with EtOAc (30 mL×4). The combined organic layers were washed with brine (40 mL×3), dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=2:1) to give the title compound as a yellow solid (1.76 g, 65%).
