To a solution of (4-prop-2-ynyl-phenyl)-methanol (10 mmol) and 5-bromo-4-cyclohexylamino-pyrimidine-2-carbonitrile (7 mmol) in DMF (20 ml) are added triethylamine (21 mmol), dichlorobis(triphenylphosphine)palladium (II) (0.35 mmol) and copper (I) iodide (0.7 mmol). The reaction mixture is heated at 85° C. ca. for 2 h. The reaction mixture is quenched with saturated ammonium chloride and extracted with AcOEt. The organic layer is washed with brine and then dried over sodium sulfate and concentrated under vacuum to give 2.6 g of crude product, which is purified by silica gel column chromatography. Yield 58%.
