実験手順
To the solution of 5-nitro-2,3,3-trimethylindole (1) (10 g) in EtOH (50 mL), hydrazine (35% in water, 6.72 g) was slowly added. The mixture was allowed to stir at room temperature for 10 min followed by the addition of palladium on carbon (Pd/C) (20% Pd/C, 1.30 g). The resultant suspension was heated at 70° C. for 2 hours, filtered, and concentrated to provide the desired product 2 (8.52 g, 100% yield): ESI-MS, Calculated [M+H]+ 175.1, Found 175.1.
