실험 절차

To a stirred mixture of 4-(6-chloro-pyrimidin-4-ylcarbamoyl)-piperidine-1-carboxylic acid benzyl ester (VIII) (0.74 g, 2.0 mmol) and 2-benzyloxyphenylboronic acid (0.50 g, 2.2 mmol) in saturated sodium carbonate solution (4 ml) and 1,4-dioxane (4 ml) was added palladium(II) acetate (0.09 g, 0.40 mmol) followed by triphenylphosphine (0.105 g, 0.400 mmol) at room temperature under an atmosphere of nitrogen. The resulting mixture was heated to reflux at 110° C. for one hour and monitored by TLC. The reaction mixture was filtered through a celite bed and the filtrate was extracted with ethyl acetate (3×100 ml). The organic layers were separated, combined, dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by preparative HPLC to afford 4-[6-(2-benzyloxy-phenyl)-pyrimidin-4-ylcarbamoyl]-piperidine-1-carboxylic acid benzyl ester (XVI) (0.65 g, 62%).
