To N-(3-aminophenyl)-2,2,2-trifluoro-N-methylactamide (302 mg) synthesized according to the method described in U.S. Pat. No. 6,344,465 B1, 4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)pyrimidine-5-carboxylic acid (A3, 627 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (545 mg) and 1-hydroxybenzotriazole monohydrate (377 mg), N,N-dimethylformamide (15 mL) and triethylamine (766 μL) were added at room temperature, the reaction vessel was sealed, and then the mixture was stirred at 100° C. for 40 minutes by using a microwave reaction system. The reaction mixture was cooled to room temperature, and then saturated aqueous sodium hydrogencarbonate and ethyl acetate were added to the mixture. The organic layer was separated, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 97 to 96% ethyl acetate in methanol) to obtain 4-(propylamino)-2-((2-(pyridin-4-yl)ethyl)amino)-N-(3-(2,2,2-trifluoro-N-methylacetamido)phenyl)pyrimidine-5-carboxamide (A7, 186 mg).
