A solution of 7-bromo-5-nitroindole (0.68 g, 2.8 mmol), hydrazine (1.0 mL, 31 mmol) and 10% Pd/C (50 mg) in 50 mL of isopropanol was stirred at reflux for 2 h. The reaction mixture was filtered and concentrated in vacuo, yielding oily residue which was subjected to column chromatography (CHCl3, neat) to produce 0.41 g (2.0 mmol, 70%) of the desired product.
