Procedure

2-(3-Acetoxypropyl)-5-tributylstannylanisole (0.92 g) and 3-bromo-1-((4-ethylpiperazin-1-yl)isoquinoline (0.37 g) were reacted in the presence of tetrakistriphenylphosphine (0.3 g) in xylene in nitrogen atmosphere for 4 hr. After cooling, the reaction solution was filtered and extracted with ethyl acetate. The resulting organic layer was washed with water and brine, dried and concentrated. The resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system), to give 0.28 g of the title compound.
