Versuchsvorschrift

To a stirred suspension of lithium aluminum hydride (12.4 g, 0.32 mol) in 300 ml of tetrahydrofuran at 0° C. under nitrogen was added dropwise a solution of N-carboethoxy-1,2-diphenylethylamine (35.0 g, 0.13 mol) in 200 ml of tetrahydrofuran. The mixture was heated to reflux for 8 hours. The mixture was cooled in an ice-water bath and water (13 ml), 15% NaOH (13 ml) and water (39 ml) were carefully added to the mixture. The mixture was warmed to ambient temperature and the precipitated salts were removed by filtration through celite. Removal of solvent gave N-methyl-1,2-diphenylethylamine, 26.8 g as a colorless oil.
