Reaction Steps

3-Bromo-1-(4-ethylpiperazin-1-yl)isoquinoline (1.72 g) and 4-(4,4-ethylenedioxypiperidin-1-yl)phenyltributylstannum (3.12 g) were reacted in the presence of tetrakistriphenylphosphine dichioride (0.5 g) in xylene (50 ml) at 140° C. for 5 hr. The reaction solution was concentrated, and ethyl acetate and an aqueous saturated solution of sodium bicarbonate were added to the resulting residue, for partitioning. The resulting organic layer was washed with water and brine, dried over magnesium sulfate and evaporated. The resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system), to give 1.27 g of the title compound as a white powder.
