Procedure
4-(2-Chloro-4-cyclobutoxy-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-N-methylbenzamide. To a degassed mixture of 2-chloro-4-cyclobutoxy-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv), N-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (1.2 equiv) and tripotassium phosphate trihydrate (3 equiv) in a 9:1 mixture of 1,4-dioxane and water (0.1 M) was added palladium 1,1-bis(diphenylphosphino)ferrocene dichloride (0.1 equiv). The reaction mixture was stirred at 80° 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 (0-30% ethyl acetate in petroleum ether) to afford the title compound (67% yield) as a yellow solid. MS (ESI) m/z 487.2 [M+1]+.
