Procedure

To a solution of 4-prop-2-ynyl-benzoic acid (6.3 mmol) and 5-bromo-4-(2,2-dimethyl-propylamino)-pyrimidine-2-carbonitrile (4.8 mmol) in DMF (30 ml), triethylamine(14.4 mmol), dichlorobis(triphenylphosphine)palladium (II) (0.48 mmol) and copper (I) iodide (0.96 mmol) are added. The reaction mixture is heated at 75° C. ca. for 18 h. Saturated aqueous solution of ammonium chloride is added to the reaction mixture and then aqueous layer is extracted with two 150 ml portions of AcOEt. The combined extracts are washed with brine, dried over sodium sulfate and concentrated under vacuum to give crude product which is purified by silica gel column chromatography. Yield: 51%. Rf=0.18 (AcOEt only)
