Reaction Steps
Lithium aluminum hydride (380 mg, 10 mmol) was added to a solution of this amide (1.50 g, 5.0 mmol) in THF (50 ml) with ice-cooling and stirring and the mixture was returned to room temperature and stirred for 15 minutes and then heated to reflux for 2 hours. Under ice-cooling and stirring, a saturated ammonium chloride solution was gradually added thereto until the reaction solution became turbid, the separated matters were filtered off through celite, the filtrate was dried over anhydrous sodium carbonate and the solvent was evaporated therefrom. The resulting residue was purified by a silica gel column chromatography (75 g of silica gel; developing solvent, ammonia-saturated methanol:chloroform=1:20) to provide 586 mg (yield 41%) of 3-[4-(2-heptylaminoethyl)piperazin-1-yl]propanol as colorless oil.
