Reaction Steps

6-Iodo-N4-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}pyrimidine-4,5-diamine hydriodide (500 mg) was dissolved in a mixed solvent of acetonitrile (14.8 mL)/triethylamine (11.0 mL), and tert-butyl 3-ethynylbenzylcarbamate (247 mg), trans-dichlorobis(triphenylphosphine)palladium(II) (31.3 mg) and copper(I) iodide (10.2 mg) were sequentially added. The title compound (376 mg) was obtained as a powder by the reaction in the same manner as in Example 9 (iv).
