Reaction Steps

3(S)-[(5-bromopyridin-2-yl)-(3-chloro-4-fluorophenyl)amino]pyrrolidine-1-carboxylic acid tert-butyl ester (300 mg, 0.64 mmol), 4-fluorophenylboric acid (98 mg, 0.7 mmol), tetrakis(triphenylphosphine)palladium (23 mg, 0.02 mmol) and a 2 M aqueous sodium carbonate solution (0.83 ml) were added to toluene (3 ml), followed by stirring under a nitrogen atmosphere at 100° C. for 10 hours. After cooling to room temperature, ethyl acetate and water were added to the reaction solution to separate the reaction solution into layers. The organic layer was washed with saturated saline, followed by drying over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=5:1). The solvent was distilled off from the purified product under reduced pressure to thereby obtain 2.55 mg of white solid 3(S)-{(3-chloro-4-fluorophenyl)-[5-(4-fluorophenyl)pyridin-2-yl]amino}pyrrolidine-1-carboxylic acid tert-butyl ester.
