Reaction Steps

The resulting 1-(piperazin-1-yl)-3-[4-(N-ethylsulfamoyl)phenyl]isoquinoline (0.49 g) was dissolved in N,N-dimethylformamide (10 ml), followed by the addition of triethylamine (290 ml) and ethylene bromohydrin (185 ml), and the reaction mixture was reacted at 50° C. overnight in nitrogen atmosphere. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water (four times) 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 0.20 g of the free compound of the title compound as a colorless powder.
