Reaction Steps
To a solution of 4-[(1-methyl-1H-benzimidazol-2-yl)oxy]aniline (0.30 g) and TEA (0.26 mL) in THF (15 mL) was added 4,6-dichloro-5-nitropyrimidine (0.24 g) at room temperature, and the mixture was stirred at room temperature for 2 h. The mixture was poured into water, and the mixture was extracted with AcOEt. The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by column chromatography (dry charge, silica gel, eluted with 5%-50% AcOEt in hexane) to give 6-chloro-N-{4-[(1-methyl-1H-benzimidazol-2-yl)oxy]phenyl}-5-nitropyrimidin-4-amine (0.24 g) as a yellow solid.
