Procedure

5-(2-Aminopyridin-4-ylamino)indole-1-carboxylic acid phenylamide (69 mg, 0.20 mmol, Production example 201-3) 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 while stirring and cooled by ice. A portion of 7.0 ml of this reaction mixture was transferred to another vessel; and the remaining portion of the reaction mixture was concentrated under reduced pressure. The residue was dissolved in N,N-dimethylformamide (1.0 ml); the similar reaction to Example 201 was performed using N,N-diethyl-1,3-diaminopropane (0.047 ml, 0.30 mmol); the crude product obtained was purified by a TLC plate (Fuji Silysia NH, developing solvent:ethyl acetate/ethanol=10/1); and the obtained crystals were suspended in ethyl acetate, filtered off, and dried to yield the title compound (3 mg, 0.006 mmol) as colorless crystals.
