Reaction Steps
A mixture of 3,5-dichloro-6-ethylpyrazine-2-carboxamide (500 mg), 5-methyl-6-(4-methylpiperazin-1-yl)pyridin-3-amine (470 mg), diisopropylethylamine (800 μL), and dioxane (10 mL) was stirred in a microwave reaction device at 150° C. for 30 minutes. After leaving to be cooled, water was added thereto, and the precipitated solid was collected by filtration and then dried under reduced pressure to obtain 5-chloro-6-ethyl-3-{[5-methyl-6-(4-methylpiperazin-1-yl)pyridin-3-yl]amino}pyrazine-2-carboxamide (210 mg) as a yellow solid.
