実験手順
A mixture of 3-aminophenoxyacetamide (10.0 g., 0.05 M), lithium aluminum hydride (6.8 g., 0.18 M) and ether (250 ml.) is refluxed under dry nitrogen for four days. It is then cooled to room temperature and water slowly added to decompose unreacted hydride. The precipitated salts are removed by filtration and the filtrate concentrated to an oil under reduced pressure. The crude oil is chromatographed on silica gel using 20% methanol/ethyl acetate as eluting agent. Concentration of appropriate fractions affords 4.83 g. (53%) of product as an oil. It is used without further purification.
