실험 절차

DIAD (197 μl) was added to a suspension of 3-((3,5-dimethoxyphenyl)ethynyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (148 mg) obtained in Example 1 (Step 1), N-Boc-3-hydroxymethylpyrrolidine (154 mg), polymer supported triphenylphosphine (up to 3.0 mmol/g, 334 mg) in THF (5.0 ml), followed by stirring at room temperature for 3 hours. The insoluble matter was filtered out, 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 (94.5 mg). Physical properties: m/z [M+H]+ 479.1
