Versuchsvorschrift

The crude product (16 mg) of (S)-3-((3,5-dimethoxyphenyl)ethynyl)-1-(pyrrolidin-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine obtained in Example 2 as an intermediate, 3-(trimethylsilyl)propionic acid (10 mg), HATU (28 mg) were dissolved in DMF (0.5 ml). DIPEA (31 μl) was added thereto, followed by stirring overnight. Ethyl acetate and a saturated aqueous sodium bicarbonate solution were added to the reaction mixture to separate the organic layer. After drying the organic layer over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography (developing solvent: ethyl acetate/methanol) to obtain the title compound as a white solid (0.7 mg). Table 1 shows the physical properties thereof.
