실험 절차

(2S,4S)-tert-butyl 2-((tert-butyldiphenylsilyloxy)methyl)-4-(methylsulfonyloxy)pyrrolidine-1-carboxylate (389 mg) obtained in Step 2 above, 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (188 mg), and potassium carbonate (363 mg) were suspended in DMF (4.0 ml), followed by stirring overnight at 80° C. Ethyl acetate and water were added thereto to separate the organic layer. The organic layer was dried over anhydrous magnesium 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, oily substance (191 mg). Physical properties: m/z [M+H]+ 699.1
