Versuchsvorschrift

N-(2-Benzyloxyethyl)-4-tributylstannylbenzamide (1.23 g) and 3-bromo-1-(4-ethylpiperazin-1-yl)isoquinoline (0.49 g) were heated under reflux in the presence of tetrakistriphenylphosphinepalladium(0) (0.13 g) in xylene in nitrogen atmosphere for 3 hr. After cooling, the reaction solution was filtered and concentrated. The resulting residue was purified by silica gel column chromatography (chloroform/methanol system). The resulting product was dissolved in ethyl acetate and extracted with 2N hydrochloric acid. The 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, to give 1-(4-ethylpiperazin-1-yl)-3-{4-[N-(2-benzyloxyethyl)carbamoyl]phenyl}isoquinoline (0.17 g) as a pale brown viscous oil.
