Reaction Steps

The resulting 1-(4-ethylpiperazin-1-yl)-3-(4-hydroxyphenyl)isoquinoline (0.53 g) was dissolved in N,N-dimethylformamide (5 ml), to which were added potassium carbonate (0.24 g) and 2-bromomethyl-1,3-dioxolane (250 ml), and the mixture was stirred at 90° C. overnight. Water was added to the reaction solution, and then the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over magnesium sulfate. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (chloroform/methanol system), to give 0.47 g of the title compound as a pale yellow oil.
