A new method for 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 yield was 51.3%, and the purity was 99.9%. This simple and effective synthetic pathway avoids gene-impurity production (as classified by the FDA Center for Drug Evaluation and Research), and the synthesis is environmentally friendly with a short reaction time.
