Reaction Steps
The obtained 2-(benzimidazol-1-yl)-4,6-dichloropyrimidine (2.08 g, 7.85 mmol) dissolved in DMF(30 ml) was cooled to −5° C., added with anhydrous potassium carbonate (3.0 g, 22 mmol) and morpholine (0.68 g. 7.85 mmol) and stirred for 30 minutes. The reaction mixture was further stirred at room temperature overnight and condensed under reduced pressure. The residue was added with methylene chloride and water and shaken for mixing. The organic layer was separated out and washed with water, dried over anhydrous magnesium sulfate and condensed. The obtained residue was purified by silica gel column chromatography to obtain 1.90 g (yield 77%) of 2-(benzimidazol-1-yl)-4-chloro-6-morpholinopyrimidine with melting point of 178° C.-181° C.
