실험 절차

PdCl2(dppf)CH2Cl2 (13 mg) was added to a mixture of (2S,4S)-tert-butyl 4-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-2-((tert-butyldiphenylsilyloxy)methyl)pyrrolidine-1-carboxylate (113 mg) obtained in Step 3 above, 1-ethynyl-3,5-dimethoxybenzene (52 mg), copper (I) iodide (6 mg), and triethylamine (0.4 ml) in THF (4 ml). After nitrogen purging, the mixture was stirred at 85° C. for 3 hours. Ethyl acetate and water were added to the reaction mixture to separate the organic layer. After washing with a saturated sodium chloride solution, the organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The resulting residue was purified by basic silica gel column chromatography (developing solvent: hexane/ethyl acetate) to obtain the title compound as a colorless, amorphous substance (100 mg). Physical properties: m/z [M+H]+ 733.3
