Reaction Steps

To a degassed mixture of 4-(2-chloro-4-cyclobutoxy-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-N-methylbenzamide (1 equiv), 4-amino-3-methoxy-N-(1-methylazetidin-3-yl)benzamide (1.2 equiv) and cesium carbonate (3 equiv) in 1,4-dioxane (0.1 M) was added palladium acetate (0.1 equiv) and 2,2′-bis-diphenylphosphanyl-[1,1′]binaphthalenyl (0.2 equiv). The reaction was stirred at 100° C. for 2 h. After the reaction was completed, the reaction mixture was cooled to room temperature and concentrated. The residue was purified by silica gel chromatography (10% MeOH in DCM) to afford the desired product (73% yield) as a yellow solid. MS (ESI) m/z 686.4 [M+H]+.
