Tetrahydrofuran → 4-Butylbenzylamine

참여 물질

반응 단계

To a suspension of 15 g of lithium aluminum hydride in 200 ml of anhydrous ethyl ether under argon was added, at room temperature, a solution of 32.0 g of 4-butylbenzamide in 200 ml of freshly distilled tetrahydrofuran. The resulting mixture was stirred at room temperature for one hour and then heated at reflux for 20 hours. The mixture was cooled and sodium sulfate decahydrate was cautiously added portionwise to the mixture until it was colorless. The mixture was stirred for 30 minutes. The mixture was filtered and the filter was washed with ether. The filtrate was evaporated in vacuo to yield 29 g (99% yield) of a liquid. The liquid was distilled by Kugelrohr distillation, bp 85° C./0.070 mm of mercury, to give the desired product as a colorless liquid.
