Sodium Chloride → HCID 22503659, compound

Participants

Reaction Steps

Subsequently, the resulting 1-(4-ethylpiperazin-1-yl)-3-[4-(2-methoxycarbonylpropyl)phenyl]isoquinoline (1.34 g) was dissolved in tetrahydrofuran (10 ml). The solution was added to a suspension of lithium aluminum hydride (0.13 g) in tetrahydrofuran (20 ml) under cooling with a cooler of sodium chloride and ice, and the mixture was further stirred for 30 min. Water (130 ml), a 5N aqueous solution of sodium hydroxide (130 ml) and water (390 ml) were added to the reaction solution in this order, and the resulting precipitates were filtered off. The solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (toluene/acetone system), to give 0.62 g of the free compound of the title compound as a pale brown viscous oil.
