A mixture of 7-(4-fluoro-phenyl)-3-iodo-imidazo[1,2-a]pyridine (10.1 g, 29.8 mmol), 1-(3-bromo-phenyl)-3-(2,2,2-trifluoro-ethyl)-urea (12.3 g, 35.8 mmol) and 2M sodium carbonate (120 mL) in dimethoxyethane (595 mL) was deoxygenated by evacuation/refill with N2 (×3). Tetrakis(triphenylphosphine)palladium (1.72 g, 1.49 mmol) was added, the resulting mixture was deoxygenated again (×3) and then heated at 80° C. under N2 overnight. The reaction was allowed to cool to RT, and solvents were removed under reduced pressure. The crude mixture was diluted with water (100 mL), EtOAc (100 mL) and DCM (100 mL) with stirring. The resulting slurry was filtered, the solid was washed with EtOAc and dried under vacuum to give the title compound (9.8 g). 1H NMR (400 MHz, DMSO-d6) δ 8.98 (1H, s), 8.61 (1H, d), 7.99 (1H, s), 7.96-7.87 (2H, m), 7.79 (2H, s), 7.45 (2H, d), 7.41-7.30 (3H, m), 7.30-7.23 (1H, m), 6.87 (1H, bt), 4.00-3.89 (2H, m).
