Reaction Steps

4-Iodo-6-phenoxypyrimidin-5-amine (1.0 g) was dissolved in a mixed solvent of acetonitrile (53 mL)/triethylamine (39 mL), and tert-butyl(dimethyl)[(2E)-2-penten-4-ynyloxy]silane (753 mg), trans-dichlorobis(triphenylphosphine)palladium(II) (112 mg) and copper(I) iodide (36.5 mg) were sequentially added. The title compound (1.07 g) was obtained as crystals by the reaction in the same manner as in Example 9 (iv).
