1-(2-Methylpropyl)-α-phenyl-1H-imidazo[4,5-c]quinoline-2-methanol (5.0 g; 15 mmol, Example 45) was dissolved in N,N-dimethylformamide (25 mL) then added to a cooled (0°-5° C.) suspension of sodium hydride (0.5 g; 16.6 mmol) in N,N-dimethylformamide (100 mL). The reaction mixture was stirred at room temperature for about one hour then combined with methyl iodide (1.4 mL; 22.6 mmol). Stirring was continued until the reaction was complete as indicated by thin layer chromatography. The reaction mixture was diluted with ether then quenched with water. The ether layer was separated, washed twice with water, dried over magnesium sulfate then evaporated under vacuum. The residue was triturated with methylene chloride/hexane to provide 4.5 g of a solid. The structure was confirmed by nuclear magnetic resonance spectroscopy.
