Reaction Steps

To a degassed mixture of 6-(2-chloro-4-(cyclopentyloxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methylbenzo[d]oxazole (1 equiv), (R)-(4-amino-3-methoxyphenyl)(2-(hydroxymethyl)aziridin-1-yl)methanone (1.2 equiv) and cesium carbonate (3 equiv) in 1,4-dioxane (0.15 M) was added palladium acetate (0.3 equiv) and 2,2′-bis-diphenylphosphanyl-[1,1′]binaphthalenyl (0.2 equiv). The reaction was stirred at 100° C. for 1 h. After the reaction was completed, the reaction mixture was cooled to room temperature and concentrated. The residue was purified by silica gel chromatography (2% MeOH in DCM) to afford the desired product (80% yield) as a white powder. MS (ESI) m/z 685.2 [M+H]+.
