4-(3,5-Dimethoxyphenyl)-3,4-dihydrobenzo[4,5]imidazo[1,2-a][1,3,5]triazin-2-amine

A new fused triazinobenzimidazole derivative, 4-(3,5-dimethoxyphenyl)-3,4-dihydrobenzo[4,5]imidazo[1,2-a][1,3,5]triazin-2-amine, was synthesized via one-step cyclocondensation reaction. The target compound was obtained in good yield and characterized by 1H NMR, 13C NMR, and HRMS. This work expands the library of aryl-substituted 3,4-dihydrobenzo[4,5]imidazo[1,2-a][1,3,5]triazines, a class of fused nitrogen-containing heterocycles of interest in medicinal chemistry.
