Reaction Steps

Trifluoroacetic acid (0.50 mL, 6.7 mmol) was added to a solution of 2-aminocarbonylamino-6-(1-tert-butoxycarbonylpyrrol-2-yl)indole-3-carboxamide (Compound 4-20, 28 mg, 0.073 mmol) in dichloromethane (0.5 mL) under ice-cooling, and the mixture was stirred for 30 minutes. 2 N Sodium hydroxide aqueous solution (3.5 mL) and water (10 mL) were added to the reaction mixture, and the whole was extracted with ethyl acetate (15 mL). The organic layer was washed with water (5 mL), brine (5 mL), and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (6.0 mg) as an off-white solid (yield 29%).
