Versuchsvorschrift
(R)-4-Benzyl-5-methylmorpholin-3-one (5.05 g, 24.6 mmol) was dissolved in THF (12.3 mL) before lithium aluminum hydride (1.87 g, 49.2 mmol) was added and the mixture stirred at RT for 1 h. The reaction mixture was quenched with ethyl acetate before a few drops of ammonium chloride was added. The colorless oil was filtered, washed with dichloromethane, concentrated, and purified by flash chromatography to give the title compound. MS (ES+): 192(M+H)+.
