Reaction Steps

A 100 mL, single-neck, round-bottomed flask was charged with 3-fluoro-4-(2-iodothieno[3,2-b]pyridin-7-yloxy)benzenamine (0.300 g, 0.7768 mmol) from Example 6, Step A, PdCl2(PPh3)2 (0.02726 g, 0.03884 mmol), tributyl(furan-2-yl)stannane (0.2931 ml, 0.9322 mmol), and dioxane (8 mL). Heat to 90° C. for 6 hours under nitrogen and cool to room temperature. The reaction mixture was diluted with brine (100 mL) and extracted with EtOAc (100 mL). The reaction mixture was purified by triturating with hot MeOH. The product (170 mg, 57%) was isolated as a brown solid. LRMS (APCI+) m/e 327 (M+1) detected.
