Procedure

To a solution of tert-butyl 2-methyl-2-(5-nitro-1H-indol-2-yl)propylcarbamate (80 mg, 0.24 mmol) in THF (9 mL) and water (2 mL) was added ammonium formate (60 mg, 0.96 mmol) followed by 10% Pd/C (50 mg). The mixture was stirred at room temperature for 45 minutes. Pd/C was filtered off and the organic solvent was removed by evaporation. The remaining aqueous phase was extracted with dichloromethane. The combined organic phases were dried over magnesium sulfate and evaporated to give tert-butyl 2-(5-amino-1H-indol-2-yl)-2-methylpropylcarbamate (58 mg, 80%).
