Procedure

2-chloro-5-fluoro-4-methylsulfanyl-pyrimidine (1.6 g, 9.0 mmol), 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 7a, (2.5 g, 6.0 mmol) and Na2CO3 (1.9 g, 18.0 mmol) were dissolved in DME (37.5 mL) and water (7.5 mL). The mixture was purged with nitrogen for 20 minutes, treated with Pd(PPh3)4, purged with nitrogen for another 20 minutes and heated to reflux overnight. After cooling to room temperature, water (35 mL) was added and the resulting suspension was stirred for 30 minutes. The precipitate was collected by filtration, washed with water and acetonitrile and dried overnight at 50° C., affording 2.3 g (88.5%) of the desired product as a white solid: 1H NMR (300 MHz, DMSO-d6) δ 8.70-8.57 (m, 2H), 8.55-8.42 (m, 2H), 8.09 (d, J=8.4 Hz, 2H), 7.45 (d, J=8.4 Hz, 2H), 2.76 (s, 3H), 2.36 (s, 3H).
