反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 5-chloro-6-ethyl-3-({3-methyl-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazine-2-carboxamide (200 mg), rac-(1R,2R)-cyclopentane-1,2-diamine dihydrochloride (230 mg), diisopropylethylamine (480 μL), and N-methylpyrrolidone (0.8 mL) was reacted in a microwave device at 150° C. for 2 hours. Water and diisopropyl ether were added thereto, and the precipitated solid was filtered to obtain rac-5-{[(1R,2R)-2-aminocyclopentyl]amino}-6-ethyl-3-({3-methyl-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazine-2-carboxamide (195 mg). was reacted in a microwave device at 150° C. for 2 hours the precipitated solid was filtered
