Procedure

N-Benzyl-2-methoxymethylmorpholine (412.3 g) is dissolved in methanol (2 liters), and thereto is added 10% palladium-carbon (33 g), and the mixture is stirred under hydrogen pressure of 9 kg/cm2 at 100° C. After completion of the reaction, palladium-carbon is filtered off, and the solvent is distilled off under atmospheric pressure to give a pale yellow oily substance. The oily substance is distilled under reduced pressure to give the title compound (212.3 g) as colorless liquid.
