Diethyl Ether → 3-(Pyridin-4-yl)butan-1-amine

Participants

Reaction Steps

Next, anhydrous ether (8 ml) was added to lithium aluminum hydride (0.16 g, 4.2 mmol) under a nitrogen atmosphere, and the mixture was stirred under ice-cooling. A solution of 3-(4-pyridyl)butyramide (0.22 g, 1.4 mmol) in anhydrous methylene chloride (8 ml) was added dropwise to the mixture over two minutes, and then the whole was stirred at room temperature overnight. Ethyl acetate (1 ml) and a 1 N aqueous sodium hydroxide solution (20 ml) were added to the reaction mixture, and the whole was extracted with chloroform (50 ml). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the target compound (0.15 g, 75%) as a pale yellow oily matter.
