실험 절차

A suspension of 3-((3,5-dimethoxyphenyl)ethynyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (62 mg) obtained in Step 1, tert-butyl 3-(methylsulfonyloxy)pyrrolidine-1-carboxylate (217 mg) obtained in Step 2, and potassium carbonate (221 mg) in DMF (2.0 ml) was stirred at 70° C. for 1 hour. Ethyl acetate and water were added thereto to separate the organic layer. 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 light-yellow, amorphous substance (36.2 mg). Physical properties: m/z [M+H]+ 465.1
