Procedure

A solution of 7-acetyl-5-nitroindole (0.2 g, 1.2 mmol) and 10% Pd/C (30 mg) in 20 mL of MeOH was stirred at reflux for 1 h. The reaction mixture was filtered and concentrated in vacuo, yielding oil (0.17 g, >95%) which was characterized by NMR and subjected to the following reaction without further purification.
