PdCl2(dppf)CH2Cl2 (1.3 mg) was added to a mixture of (S)-1-(3-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)pyrrolidin-1-yl)-4-(dimethylamino)but-2-en-1-one (8.0 mg) obtained in Step 1, 1-ethynyl-3-methoxybenzene (4.0 mg), copper (I) iodide (0.6 mg), and triethylamine (8.6 μl) in THF (1.0 ml). After nitrogen purging, the resulting mixture was stirred at 80° C. overnight. The reaction mixture was diluted with ethyl acetate and methanol. The resulting diluted solution was treated with basic silica gel, and then concentrated. The resulting residue was purified by reversed-phase HPLC purification (water/acetonitrile (0.1% formic acid)) to obtain the title compound as a colorless, amorphous substance (1.4 mg). Table 2 shows the physical properties thereof.
