実験手順
N4-[(1S)-2-{[tert-Butyl(dimethyl)silyl]oxy}-1-(4-{[tert-butyl(dimethyl)silyl]oxy}benzyl)ethyl]quinoline-3,4-diamine (23.46 g, 43.6 mmol) was dissolved in 400 mL of dry 1,2-dichloroethane and the yellow solution was stirred under N2. Ethyl 2-chloroethanimidoate hydrochloride (13.8 g, 87.2 mmol) was then added and the reaction mixture was heated to 70° C. overnight. The reaction mixture was then cooled and treated with 300 mL of saturated NaHCO3 solution. The layers were separated and the organic portion was washed sequentially with saturated NaHCO3 solution and brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. Chromatography (SiO2, 10-60% ethyl acetate/hexanes) gave 1-[(1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-(4-{[tert-butyl(dimethyl)silyl]oxy}benzyl)ethyl]-2-(chloromethyl)-1H-imidazo[4,5-c]quinoline (21.11 g) as a brown foam.
