Procedure

To a solution of 50 mg (0.2 mmol) of 4-(5-methyl-3-phenyl-isoxazole-4-yl)-pyrimidin-2-ylamine in 1 mL of toluene was added successively 63 μL (0.6 mmol) of bromobenzene, 10 mg of tris(dibenzylideneacetone) dipalladium, 10 mg of BINAP and 39 mg (0.4 mmol) of sodium tert-butoxide. The mixture was heated at reflux for 16 h, diluted with ethyl acetate, filtered, washed successively with saturated aqueous sodium bicarbonate and brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography over silica gel eluted with ethyl acetate-hexanes 1:3, to afford 24 mg (36%) of the title compound as a yellow oil.
