Versuchsvorschrift

A mixture of 5-chloro-6-ethyl-3-({4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazine-2-carboxamide (21 mg), tert-butyl (2-aminoethyl)methylcarbamate (31 mg), diisopropylethylamine (16 μL), and N-methylpyrrolidone (0.3 mL) was stirred at 140° C. for 2 hours and a half. To the reaction mixture was added PS-benzaldehyde (Biotage, 150 mg) at room temperature, N,N-dimethylformamide (1 mL) was added thereto, followed by stirring for 2 hours, and the insoluble matter was filtered. The filtrate was evaporated under reduced pressure and the obtained residue were added methanol (0.5 mL) and a 4 M hydrogen chloride-dioxane solution (0.45 mL), followed by stirring at room temperature for 8 hours. The solvent was evaporated under reduced pressure, and to the obtained residue were added tetrahydrofuran (0.9 mL) and a saturated aqueous sodium hydrogen carbonate solution (1 mL), followed by stirring at room temperature. Acryloyl chloride (8 μL) and tetrahydrofuran (0.1 mL) were added thereto at room temperature, followed by stirring for 4 hours. The reaction mixture was extracted with chloroform. The solvent of the organic phase was evaporated under reduced pressure and the obtained residue was purified by preparative HPLC (methanol/0.1% aqueous formic acid solution) to obtain 5-({2-[acryloyl (methyl)amino]ethyl}amino)-6-ethyl-3-({4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazine-2-carboxamide (1 mg).
