Procedure

The crude product (5.6 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, 4-(dimethylamino)but-2-enoic acid hydrochloride (6.3 mg), and HATU (15 mg) were dissolved in DMF (1.0 ml). DIPEA (50 μl) was added thereto, followed by stirring overnight. Chloroform and water were added to the reaction mixture to separate the organic layer. After being washed with a saturated sodium chloride solution, the organic layer was dried over anhydrous sodium sulfate, and the solvent was then distilled off under reduced pressure. The resulting residue was purified by preparative reversed-phase HPLC purification (water/acetonitrile (0.1% formic acid)) to obtain the title compound as a colorless, amorphous substance (2.3 mg). Table 1 shows the physical properties thereof.
