Versuchsvorschrift

To a solution of N4-{3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}-6-iodopyrimidine-4,5-diamine (300 mg) and 4-pentyn-1-ol (65 mg) in acetonitrile-triethylamine (6.0 mL-4.5 mL) were added bis(triphenylphosphine)palladium(II) dichloride (22.5 mg) and copper(I) iodide (7.3 mg) at room temperature, and the mixture was stirred at room temperature under an argon atmosphere for 24 hrs. 4-Pentyn-1-ol (65 mg), bis(triphenylphosphine)palladium(II) dichloride (22.5 mg) and copper(I) iodide (7.3 mg) were added to the reaction system and the mixture was stirred at 60° C. for 2 hrs. After concentration under reduced pressure, the residue was separated and purified by column chromatography (basic silica gel, eluent, ethyl acetate→methanol:ethyl acetate=1:19) to give the title compound (157.2 mg) as a yellow solid.
