Reaction Steps

Bis-(4-methoxybenzyl)-[5-(2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-pyrimidin-2-yl]-amine (1.65 g, 3.05 mmol) was suspended in dimethylformamide (20 ml), followed by addition of 2-chloro-4-iodopyridine (805 mg, 3.36 mmol), palladium acetate (35 mg, 0.156 mmol), triphenyl phosphine (81 mg, 0.309 mmol) and potassium phosphate (1.95 g, 14.1 mmol), and argon gas was blown for 10 minutes while irradiating ultrasonic wave. The reaction mixture was stirred at 100° C. for 1 hour, and cooled to room temperature, followed by addition of water (50 ml). The mixture was extracted with ethyl acetate (100 ml) and dichloromethane (100 ml), and the combined organic layers were washed with brine, followed by drying over sodium sulfate. After filtering off the drying agent, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (dichloromethane/methanol=50/1), followed by suspension of the residue in ethyl acetate/hexane (10 ml/50 ml). The precipitate was filtered, and washed with hexane, followed by drying under reduced pressure, to obtain {5-[7-(2-chloro-pyridin-4-yl)-2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl]-pyrimidin-2-yl}-bis-(4-methoxy-benzyl)-amine as a yellow powder (1.75 g, 88%).
