5-(2-Aminopyridin-4-ylamino)indole-1-carboxylic acid phenylamide (69 mg, 0.20 mmol) was dissolved in tetrahydrofuran (14 ml); triethylamine (0.055 ml, 0.40 mmol) was added thereto; and phenyl chloroformate (0.038 ml, 0.30 mmol) was added thereto while cooling with ice and stirring. A portion of 7.0 ml of the reaction mixture was transferred to another vessel and concentrated under reduced pressure. After the residue was dissolved in N,N-dimethylformamide (1.0 ml), the similar reaction to Example 27 was performed by use of diethylamine (0.031 ml, 0.30 mmol). The obtained crude product was purified by TLC plate (Fuji Silysia NH, developing solvent: ethyl acetate) to yield the title compound (2.0 mg, 0.005 mmol) as pale yellow crystals.
