実験手順

6-Iodo-N4-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}pyrimidine-4,5-diamine hydroiodide (200 mg) was dissolved in a mixed solvent of acetonitrile (7.6 mL)/triethylamine (5.72 mL), 3-ethynylaniline (0.0574 mL), trans-dichlorobis(triphenylphosphine)palladium(II) (15.4 mg) and copper(I) iodide (5.3 mg) were sequentially added, and the mixture was stirred under a nitrogen stream at room temperature for 1.5 hrs. The reaction mixture was concentrated under reduced pressure and the residue was separated and purified by silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→ethyl acetate:methanol=80:20) to give the title compound (157 mg).
