Reaction Steps

To a solution of 2-chloro-N-(cis-3-methyl-tetrahydro-2H-pyran-4-yl)-5-nitropyrimidin-4-amine (115 mg) in acetonitrile (5 mL) was added potassium carbonate (300 mg) and benzimidazole (150 mg). The mixture was stirred at 70° C. for 2.5 hours. After diluting with 70 mL EtOAc, the mixture was washed with brine, dried over sodium sulfate, and concentrated in vacuo. Column chromatography (50→100% EtOAc/hexanes) provided 99 mg of the title compound.
