実験手順
To a solution of 5-fluoro-2-methoxyphenyl boronic acid (0.20 g, 1.1 mmol) in a mixture of THF and water (6 ml, 1:1), benzyl 3-(6-chloropyrimidin-4-ylcarbamoyl)piperidine-1-carboxylate (0.35 g, 1.0 mmol) was added at 0° C. followed by palladium acetate (12 mg, 0.054 mmol), PPh3 (31 mg, 0.12 mmol) and saturated solution of sodium carbonate (2 ml). The reaction mixture was stirred at room temperature for 30 h and then filtered through a celite bed which was washed with ethyl acetate. The aqueous layer was extracted with ethyl acetate, the organic layers were combined, washed with brine, dried and evaporated under reduced pressure. The crude product was purified by column chromatography, using hexane/ethyl acetate (4:1) as eluent, to provide 0.31 g (yield: 53.8%) of 3-[6-(5-fluoro-2-methoxy-phenyl)-pyrimidin-4-ylcarbamoyl]-piperidine-1-carboxylic acid benzyl ester
