Reaction Steps
To a solution of 2,4-dichloropyrimidine (1 mmol) and 5-Aminobenzimidazole (1 mmol) in 5 ml EtOH, was added Et3N (1 mmol). The reaction mixture was refluxed for 5 hours. After removal of the solvent in vacuo and addition of H2O, the mixture was extracted with EtOAc. The organic layers were combined, washed with a saturated NaCl aqueous solution, dried over anhydrous Na2SO4, and concentrated in vacuo. The residue was purified by column chromatography to give N-(2-chloropyrimidin-4-yl)-1H-benzo[d]imidazol-5-amine in a yield of 80%.
