Versuchsvorschrift

To a solution of 4-((4-chloro-5-iodopyrimidin-2-yl)amino)benzonitrile (J12, 100 mg) and tert-butyl(4-pentynyl)carbamate (77 mg) in N,N-dimethylformamide (3 mL), bis(triphenylphosphine)palladium(II) dichloride (20 mg), triethylamine (195 μL) and copper(I) iodide (11 mg) were added at room temperature, and the mixture was stirred at the same temperature for 1 hour. To the reaction mixture, saturated aqueous ammonium chloride and ethyl acetate were added. The organic layer was separated, washed with saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained solid matter was washed with a mixture of hexane and ethyl acetate (5:1), and then air-dried to obtain tert-butyl (5-(4-chloro-2-((4-cyanophenyl)amino)pyrimidin-5-yl)-4-pentyn-1-yl)carbamate (T5, 73 mg) as pale yellow solid.
