Procedure

2-Chloro-5-fluoro-4-methylsulfanyl-pyrimidine (34.1 g, 191.0 mmol), 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 44a, (53.0 g, 127.3 mmol) and Na2CO3 (40.5 g, 381.9 mmol) were dissolved in a mixture of DME (795 mL) and water (159 mL). The mixture was purged with nitrogen for 20 minutes and treated with Pd(PPh3)4 (7.4 g, 6.6 mmol). After purging with nitrogen for another 20 minutes, the reaction was heated to reflux overnight, cooled to room temperature and diluted with water (600 mL). The resulting suspension was stirred at room temperature for 30 minutes and the precipitate was then collected by filtration, washed with water and acetonitrile and dried at 50° C. to afford 48.2 g of 5-fluoro-3-[5-fluoro-4-(methylthio)pyrimidin-2-yl]-1-tosyl-1H-pyrrolo[2,3-b]pyridine as a white solid.
