Versuchsvorschrift

A solution of 7.66 g of the N-benzyl-2-chloro-N-isopropylacetamide in 20 ml of dry diethyl ether was added dropwise to a suspension of 1.29 g of lithium aluminum hydride in 300 ml of dry diethyl ether with stirring under ice-cooling, and the mixture was heated under reflux for 4 hours. After the reaction mixture was cooled, and to the cooled reaction mixture was added dropwise water with stirring under ice-cooling. Insoluble materials were filtered off. The filtrate was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified with silica gel column chromatography (eluent: chloroform) to obtain 3.61 g of 2-(N-isopropylbenzylamino)ethyl chloride in an oil.
