PROCEDURE

实验过程

A solution of 2-[2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]ethanol (1.0 g, 3.7 mmol) in N,N-dimethylformamide was added dropwise to a suspension of sodium hydride (0.19 g of a 60% dispersion in mineral oil, 4.8 mmol) in N,N-dimethylformamide (20 ml). The reaction was maintained for 2 hours followed by the dropwise addition of benzyl 3-bromopropyl ether (0.72 ml, 4.1 mmol). The reaction was stirred overnight at 100° C., quenched by pouring over ice, and extracted with ethyl acetate. The organic fractions were washed with water, dried (MgSO4), filtered, and concentrated. The crude product was purified by flash column chromatography (silica gel, 4:1 ethyl acetate/hexanes) to provide 0.45 g of 1-{2-[3-(benzyloxy)propoxy]ethyl}-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinoline as a brown oil
