Trichloroacetyl isocyanate (48 μL, 0.36 mmol) was added to a solution of 6-acetylamino-2-aminoindole-3-carboxamide (Reference compound 15-1, 26 mg, 0.11 mmol) in anhydrous tetrahydrofuran (1.5 mL), and the mixture was stirred at room temperature for 18 hours. 2.0 M Ammonia in methanol solution (2.0 mL, 4.0 mmol) was added thereto, and the mixture was stirred at room temperature for 6 hours. The precipitated solid was separated by filtration using methanol (0.5 mL), and dried under reduced pressure to give the title compound (13 mg) as a colorless solid (yield 43%).
