Procedure

2-Methyl-2-(5-nitro-1H-indol-2-yl)-propanoic acid (4.12 g, 16.6 mmol) was dissolved in acetonitrile (80 mL). EDC (3.80 g, 0.020 mmol), HOBt (2.70 g, 0.020 mmol), Et3N (6.9 mL, 0.050 mmol) and ammonium chloride (1.34 g, 0.025 mmol) were added and the mixture was stirred overnight at room temperature. Water was added and the mixture was extracted with ethylacetate. Combined organic phases were washed with brine, dried over magnesium sulfate and dried to give 2-methyl-2-(5-nitro-1H-indol-2-yl)propanamide (4.3 g, 99%).
