Reaction Steps

To a solution of 4,6-dichloro-2-(methylsulfanyl)pyrimidine (5 g) in N,N-dimethylformamide (50 mL) were added potassium carbonate (5.3 g) and 2-(difluoromethyl)-1H-benzimidazole (3.9 g), and the mixture was stirred at room temperature for 5 hours. To the reaction mixture was added water, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and then the residue was purified by silica gel column chromatography (hexane:ethyl acetate) to obtain 1-[6-chloro-2-(methylsulfanyl)pyrimidin-4-yl]-2-(difluoromethyl)-1H-benzimidazole (5.49 g) as a white powder.
