Reaction Steps

A solution of bis-(4-methoxy-benzyl)-[5-(2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-pyrimidin-2-yl]-amine (200 mg, 0.370 mmol), 4-bromobenzoic acid methyl ester (95 mg, 0.444 mmol), palladium acetate (10.0 mg, 0.0444 mmol), S-Phos (36.4 mg, 0.0888 mmol) and potassium phosphate (157 mg, 0.740 mmol) in dimethylformamide (3 ml) was degassed under ultrasonic irradiation, and stirred at 100° C. for 3 hours. To this, water was added, and the precipitate was filtered, which was subsequently dissolved in dichloromethane, and dried over sodium sulfate, followed by concentration under reduced pressure. Purification by silica gel column chromatography (dichloromethane/methanol=200/1) afforded 4-(4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidin-7-yl)-benzoic acid methyl ester as a yellow powder (143.5 mg, Yield 57%).
