6-Nitro-2-phenyl-1H-indole (175 mg, 0.73 mmol), ammonium chloride (80 mg, 1.47 mmol) and iron powder (205 mg, 3.68 mmol) were suspended in ethanol/water (4 mL/2 mL) and heated at 70° C. for 2 h. After cooling, the solution was filtrated through a pad of Celite®, which was washed with ethanol. The organic layer was evaporated into vacuo to obtain a solid, which was purified by column chromatography eluting using a gradient (ethyl acetate/hexanes 10:90 v/v to ethyl acetate/hexanes 50:50 v/v) to afford 54 mg (35%) of the title compound.
