実験手順

4-(4-Tributylstannylphenyl)-2-butanone (2.46 g) and 3-bromo-1-(4-ethylpiperazin-1-yl)isoquinoline (1.41 g) were heated under reflux in the presence of tetrakistriphenylphosphinepalladium(0) (0.22 g) in xylene in nitrogen atmosphere overnight. After cooling, the reaction solution was diluted with ethyl acetate and filtered. The filtrate was extracted in 2N hydrochloric acid, and the resulting aqueous layer was washed with ethyl acetate, adjusted to pH 10 with a 8N aqueous solution of sodium hydroxide, and then extracted with ethyl acetate. The extract was washed with a 10% aqueous solution of sodium carbonate and brine, and dried over magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (toluene/acetone system), to give 1-(4-ethylpiperazin-1-yl)-3-[4-(3-oxobutyl)phenyl]isoquinoline (1.07 g) as a pale yellow viscous oil.
