Procedure

To a mixture of 5-(3-{[(2E)-4-chlorobuta-2-enoyl]amino}phenoxy)-6-isopropyl-3-{[4-(4-methylpiperazin-1-yl)phenyl]amino}pyrazine-2-carboxamide (80 mg) and N,N-dimethylformamide (800 μL) were added diisopropylethylamine (25 μL) and morpholine (11 μL), followed by stirring at room temperature overnight. Water was added thereto, and the precipitated solid was collected by filtration and purified by silica gel column chromatography (eluent; chloroform:methanol:28% aqueous ammonia=1:0:0-100:10:1). Diisopropyl ether was added thereto and the precipitated solid was collected by filtration and then dried under reduced pressure to obtain 6-isopropyl-3-{[4-(4-methylpiperazin-1-yl)phenyl]amino}-5-(3-{[(2E)-4-(morpholin-4-yl)but-2-enoyl]amino}phenoxy)pyrazine-2-carboxamide (27 mg) as a solid.
