Participants

Reaction Steps

N-[5-(4-chloromethylbenzoylamino)-2-methylphenyl]-4-(3-pyridyl)-2-pyrimidine-amine (1 g, 2.33 mmol) was dissolved in tetrahydrofuran (20 ml), pyridine (360 μl, 4.66 mmol) was added thereto, and the mixture was stirred for 30 minutes. 1-Amino-4-methylpiperazine (418 μl, 3.49 mmol) was added, and the mixture was refluxed for 12 hours and filtered. The filtrate was concentrated, subjected to column chromatography (eluent: chloroform:methanol=3:1(v/v)), concentrated again, and then crystallized from dimethylether to give 4-(4-methylpiperazin-1-ylaminomethyl)-N-[4-methyl-3-(4-(pyridin-3-yl)pyrimidin-2-yl)aminophenyl]benzamide (880 mg).
