実験手順

7-Bromo-2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinoline (1.00 g, 2.46 mmol), phenyl vinyl sulfone (0.852 g, 5.06 mmol), palladium(II) acetate (12 mg, 0.05 mmol), and tris(2-tolyl)phosphine (32 mg, 0.10 mmol) were added to a pressure tube. Triethylamine (1.37 mL, 9.84 mmol) and acetonitrile (5 mL) were added. The tube was flushed with nitrogen, sealed with a TEFLON plug and heated at 100° C. for 96 hours. The reaction mixture was cooled to ambient temperature and concentrated under reduced pressure. The residue was initially purified by flash column chromatography (silica gel, eluting with a gradient of 50%-100% ethyl acetate in hexanes, followed by a gradient of 2%-6% methanol in ethyl acetate). Recrystallization of the resulting solid from acetonitrile provided 0.600 g 7-(2-benzenesulfonylvinyl)-2-ethoxymethyl-1-(3-isopropoxypropyl)-1H-imidazo[4,5-c]quinoline as a yellow crystalline solid.
