Reaction Steps

The resulting 1-(4-ethylpiperazin-1-yl)-3-(4-hydroxyphenyl)isoquinoline (0.57 g) was dissolved in N,N-dimethylformamide (5 ml), to which were added potassium carbonate (0.24 g) and ethyl bromoacetate (210 ml), and the mixture was stirred at room temperature for 2 days. Water was added to the reaction solution, followed by the extraction with ethyl acetate. The extract 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 (chloroform/methanol system), to give obtain 1-(4-ethylpiperazin-1-yl)-3-[4-(ethoxycarbonylmethoxy)phenyl]isoquinoline (0.57 g) as a pale yellow viscous oil.
