Reaction Steps

To a solution of {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 (50 mg) obtained in Step A, sodium t-butoxide (50 mg) and palladium dibenzylideneacetone complex (6 mg) suspended in toluene (1.5 ml), argon gas was blown for 5 minutes. Morpholine (10 μl) and 2,8,9-triisobutyl-2,5,8,9-tetraaza-1-phospha-bicyclo[3.3.3]undecane (6.9 mg) were added, followed by stirring at 110° C. for 6 hours. The reaction mixture was cooled to room temperature, and water (5 ml) was added, followed by extraction with dichloromethane (10 ml×2). The combined organic layers were washed with brine, and dried over sodium sulfate. After the drying agent was filtered off, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (dichloromethane/methanol=50/1), to obtain a yellow amorphous (46 mg, 85%).
