実験手順
CuI (0.2 equiv., 0.256 mmol, 0.049 g), dichlorobis(triphenylphosphine)-palladium(II) (0.1 equiv., 0.13 mmol, 0.090 g), triethylamine (1.0 equiv., 1.28 mmol, 0.129 g), (trimethylsilyl)acetylene (10.0 equiv., 12.8 mmol, 1.26 g) and KI (10.0 equiv., 12.8 mmol, 2.12 g) were added to a mixture of 6-(6-bromo-pyridin-3-yl)-pyrido-[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-one (21) (1.0 equiv., 1.28 mmol, 0.50 g) in dry DMF (10 ml). The reaction mixture was stirred at room temperature under N2 atmosphere for 24 h. After addition of a second portion of CuI (0.20 equiv., 0.256 mmol, 0.049 g) and dichlorobis(triphenylphosphine)-palladium(II) (0.1 equiv., 0.13 mmol, 0.090 g), the reaction mixture was further stirred at 60° C. for 17 h. The solvent was evaporated under reduced pressure and the pasty residue was mixed with dichloromethane and washed with water. The organic layer was evaporated under reduced pressure and the residue purified by column chromatography (ethyl acetate/heptane 60:40) to afford 6-[6-[(trimethylsilanyl)ethynyl]-pyridin-3-yl]-pyrido[2′,1′:2,3]-imidazo[4,5-c]isoquinolin-5(6H)-one (I9) (0.50 g, yield=96%, purity (LC)=95%).
