Procedure

To a solution of N.-(4-prop-2-ynyl-phenyl)-methanesulfonamide (1.0 mmol) and 5-bromo-4-(2,2-dimethyl-propylamino)-pyrimidine-2-carbonitrile (0.5 mmol) in DMF (5 ml), triethylamine (1.5 mmol), dichlorobis-dichlorobis(triphenylphosphine)palladium (II) (0.05 mmol) and copper (I) iodide (0.1 mmol) is added. The reaction mixture is heated at 70° C. ca. for 2.5 h. The mixture is quenched with saturated ammonium chloride and extracted with two 50 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: 60.7%. Rf=0.55 (n-hexane:AcOEt=1:1)
