A DMF solution (4 ml) of [tert-butoxycarbonyl-(4-chloro-pyridin-2-yl)-amino]-acetic acid methyl ester (200 mg, 0.667 mmol) obtained in Step A, bis-(4-methoxy-benzyl)-[5-(2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-pyrimidin-2-yl]-amine (300 mg, 0.556 mmol), palladium acetate (12.5 mg, 0.0556 mmol), S-Phos (46 mg, 0.111 mmol) and potassium phosphate (354 mg, 1.67 mmol) was deaerated under irradiation of ultrasonic wave, followed by stirring at 100° C. for 1 hour under a nitrogen atmosphere. The reaction mixture was cooled to room temperature, and diluted with water, followed by extraction with dichloromethane (30 ml×2). The organic layers were combined, and washed with saturated aqueous sodium chloride solution. After the organic layer was dried over magnesium sulfate, the magnesium sulfate was filtered off, and the filtrate was concentrated under reduced pressure, followed by purification of the residue by silica gel column chromatography (dichloromethane/methanol=50:1), to obtain {[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)-pyridin-2-yl]-tert-butoxycarbonyl-amino}-acetic acid methyl ester as a yellow solid (400 mg, 90%).
