Reaction Steps

A mixture of N2-(2,4-dichlorophenyl)-N7,N7-diethyl-4-fluoro-1H-benzimidazole-2,7-diamine (96.7 mg, 0.263 mmol), 1,3-dibromopropane (72.6 mg, 0.360 mmol) and potassium carbonate (113 mg, 0.819 mmol) in N,N-dimethylformamide (6 mL) was stirred at 80° C. for 3 hr. After ethyl acetate was added, the resultant mixture was washed with water and brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with ethyl acetate and preparative HPLC eluting with a 10-100% acetonitrile/water gradient mixture to give the title compound as a pale pink solid (38.2 mg, 0.0938 mmol, 36%).
