Reaction Steps

To a degassed mixture of 2-chloro-5-(2-methoxypyridin-4- yl)-4-((tetrahydro-2H-pyran-4-yl)oxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv), 4-amino-3-methoxy-N-methylbenzamide (1.1 equiv) and cesium carbonate (3 equiv) in 1,4-dioxane (0.175 M) was added palladium acetate (0.3 equiv) and 2,2′-bis-diphenylphosphanyl-[1,1′]binaphthalenyl (0.6 equiv). The reaction was stirred at 100° C. for 2 h. After the reaction was complete, the reaction mixture was cooled to room temperature, filtered and concentrated to afford the crude product (95% yield, crude) as a brown solid which was used in the next step without further purification . MS (ESI) m/z 635.3 [M+1]+.
