Reaction Steps

1-Chloro-7-methoxy-3-phenylisoquinoline (0.20 g) was reacted with N-ethylpiperazine (3 ml) and potassium carbonate (0.2 g) at 120° C. for 5 hr. To the reaction solution were added ethyl acetate and water, and it was extracted with ethyl acetate. The resulting organic layer was washed with water and brine, and dried over magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system), to give 0.18 g of the free compound of the title compound as a pale yellow oil.
