Reaction Steps

A mixture of 6-methyl-4-(3-nitrophenyl)-2-phenyl-5-pyrimidinecarboxamide (5 g), formalin (37%, 1.35 ml), N-methylpiperazine (2.25 g), ethanol (50 ml) and 1,2-dichloroethane (25 ml) was refluxed for 6 hours. After evaporating the solvent in vacuo, the residue was chromatographed on alumina (200 ml) and eluted with chloroform. The fractions containing the object compound were combined and concentrated under reduced pressure. The residue was recrystallized from diethyl ether to give 6-methyl-N-(4-methylpiperazin-1-ylmethyl)-4-(3-nitrophenyl)-2-phenyl-5-pyrimidinecarboxamide (1.90 g).
