Reaction Steps

1-(1-Methylpiperazin-4-yl)-3-[4-(ethoxycarbonylmethoxy)phenyl]isoquinoline (320 mg) was dissolved in tetrahydrofuran (5 ml), to which was added lithium aluminium hydride (16 mg) under ice-cooling, followed by stirring for 5 min. To the resulting reaction mixture were then added water (16 ml), 5N sodium hydroxide (16 ml) and water (48 ml) in this order. After diluting with ethyl acetate, it was filtered through Celite and evaporated. The resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system), which was converted into a hydrochloride in a conventional manner, and then recrystallized from in ethanol, to give the hydrochlroide of the title compound as yellow crystals (105 mg, yield; 50%).
