imatinib synthesis is described by using the C–N coupling reaction of 4-(4-methylpiperazine-1-methyl)benzamide with N-(5-bromo-2-tolyl)-4-(3-pyridyl)pyrimidin-2-amine to form imatinib. In this synthetic route, the high efficiency and high selectivity of nano-ZnO as a catalyst is key to the mild hydrolysis of 4-(4-methylpiperazine-1-methyl)benzonitrile into the corresponding amide. The total imatinib
