Reaction Steps

4-(Piperidin-1-yl)piperidine (342 mg, 2.03 mmols) and cesium carbonate (764 mg, 2.34 mmols) were added to DMF solution (10 ml) of 2-chloro-5-bromopyrimidine (300 mg, 1.56 mmols), and stirred at room temperature for 16 hours. Water was added to the reaction mixture, which was then extracted with ethyl acetate. The organic layer was washed with saturated saline solution, dried with anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was purified through silica gel column chromatography (C-300, chloroform/methanol=100/3) to obtain the entitled compound (349 mg, 69%).
