反応手順
A 4 dram vial containing a stir bar was charged sequentially with copper(I) iodide (0.038 g), potassium phosphate (0.890 g), pyrazole (0.164 g), 7-bromo-2-ethoxymethyl-1-(3-methoxypropyl)-1H-imidazo[4,5-c]quinolin-4-amine (0.786 g), (±)-trans-1,2-diaminocyclohexane (0.030 mL), and anhydrous 1,4-dioxane (2 mL). The vial was flushed with nitrogen, capped, and placed in an oil bath at 110° C. After 15.5 hours, the reaction was cooled to room temperature and purified by flash column chromatography using a gradient of CMA/chloroform as the eluent. Subsequent recrystallization from acetonitrile yielded 0.190 g of 2-ethoxymethyl-1-(3-methoxypropyl)-7-(pyrazol-1-yl)-1H-imidazo[4,5-c]quinolin-4-amine as a white solid, mp 159.0–160.0° C.
