Procedure

N-(4-bromo-2-methoxyphenyl)-5-chloro-4-(imidazo[1,2-a]pyridin-3-yl)pyrimidin-2-amine (107 mg, 0.25 mmol), 2,6-dimethylpiperazine (28.4 mg, 0.25 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (5.75 mg, 9.94 µmol), diacetoxypalladium (1.116 mg, 4.97 µmol) and cesium carbonate (162 mg, 0.50 mmol) were suspended in 1,4-dioxane (2 mL) . The reaction was purged with nitrogen and heated to 140 °C for 6 hours in an oil bath. Control LC/MS : no traces of expected product.
