実験手順

Under an argon atmosphere, EDC hydrochloride (39 mg) and HOBT (3 mg) were added to a solution of 2-amino-5-[4-(methyl-pyrimidin-2-ylamino)phenyl]pent-4-enoic acid methyl ester (51 mg) and 2-chloro-6-fluorobenzoic acid in dichloromethane (1.5 ml), and the resulting mixture was stirred at room temperature for 28 hours. To the reaction solution, 1N hydrochloric acid was added, and the resulting mixture was extracted with ethyl acetate. Organic layer was washed with saturated aqueous sodium hydrogen carbonate solution and dried over anhydrous sodium sulfate. After removing anhydrous sodium sulfate by filtration, the filtrate was concentrated. The residue was purified by thin layer chromatography (silica gel, mobile phase: hexane/ethyl acetate=1/2) to obtain (E)-2-(2-chloro-6-fluorobenzamido)-5-[4-(methyl-pyrimidin-2-ylamino)phenyl]pent-4-enoic acid methyl ester (39 mg).
