Procedure

To a solution of 5-iodo-4-(morpholin-4-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine (P1) (500 mg, 1.09 mmol) and 4,4,5,5-tetramethyl-1,3,2-dioxaborolane (543 mg, 4.24 mmol) in 1,4-dioxane (20 mL) was added tris(dibenzylideneacetone)dipalladium(0) (99.7 mg, 0.109 mmol), triethylamine (439 mg, 4.34 mmol) and 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (XPhos, 51.8 mg, 0.109 mmol), and the reaction mixture was heated at 95° C. for 18 hours. After cooling to room temperature, the reaction mixture was diluted with water (100 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with saturated aqueous sodium chloride solution (100 mL), dried over sodium sulfate, filtered, and concentrated in vacuo. Purification via silica gel chromatography (Gradient: 0% to 30% ethyl acetate in petroleum ether) afforded the product as a yellow oil. Yield: 415 mg, 0.901 mmol, 83%.
