Procedure

The crude product (100 mg) of (S)-5-((3,5-dimethoxyphenyl)ethynyl)-7-(pyrrolidin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (i.e., the intermediate obtained in Example 38 (Step 4)) was suspended in chloroform (3.0 ml). DIPEA (117 μl) was added to the suspension, and the mixture was cooled to 0° C. A solution of 4-bromobut-2-enoyl chloride (46 mg) obtained in Example 16 (Step 1) in chloroform (0.3 ml) was added thereto dropwise, and the resulting mixture was stirred at room temperature for 15 minutes. After halting the reaction using a saturated aqueous sodium bicarbonate solution, the resulting product was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to obtain the title compound as a crude product (140 mg). Physical properties: m/z[M+H]+509.9, 511.9
