Procedure

To a solution of 6-((3-fluorophenyl)amino)-4-(propylamino)nicotinic acid (S16, 87 mg), (S)-tert-butyl (1-((3-aminophenyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (B9, 115 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (115 mg) and 1-hydroxybenzotriazole monohydrate (81 mg) in N,N-dimethylformamide (2 mL), N,N-diisopropylethylamine (157 μL) was added at room temperature, and the mixture was stirred at 40° C. for 15 hours. The reaction mixture was cooled to room temperature, and then saturated aqueous sodium hydrogencarbonate was added to the reaction mixture. The solid matter was taken by filtration, washed with water, and then purified by silica gel column chromatography (eluent, 75 to 35% hexane in ethyl acetate) to obtain (S)-tert-butyl (1-((3-(6-((3-fluorophenyl)amino)-4-(propylamino)nicotinamido)phenyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (S17, 123 mg).
