Reaction Steps

In a 20 mL microwave tube, 2-Bromo-6-fluoropyridine (L) (682 mg, 3.3 mmol, 1.2 equiv.), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (B)(1.1 g, 2.8 mmol, 1 equiv.) and Pd(PPh3)4 (323 mg, 0.28 mmol), 0.1 equiv.) were suspended in a mixture of DME (10 mL) and aqueous Na2CO3 2M (3 mL). The container was sealed and the reaction mixture was exposed to microwave irradiation for 30 min at 160° C. The resulting mixture was diluted in ethyl acetate, washed with water and dried over anhydrous Na2SO4. The crude material was purified by flash chromatography on silica gel, eluting with hexanes/ethyl acetate mixtures (90:10 to 60:40). The title compound J was isolated as a pale yellow solid (2.1 g, 50%).
