실험 절차

To a solution of 2-(N-benzylamino)ethyl hydrogen sulfate (28 g) in a mixture of water (36.3 ml) and 40% sodium hydroxide aqueous solution (12.1 ml) was added 2,2-bis(methoxymethyl)oxirane (16.0 g) at room temperature over 30 minutes. After stirring at room temperature for 87 hours, 40% sodium hydroxide aqueous solution (73 ml) was added dropwise to the mixture over 20 minutes. The mixture was stirred at room temperature for 1 hour and at 40° C. for 20 hours, and extracted with ethyl acetate (100 ml×3). The organic layer was extracted with 1N hydrochloric acid (×6). The combined extracts were neutralized with sodium hydroxide, and then added sodium chloride, and extracted with ethyl acetate (100 ml×3). The combined extracts were washed with brine, dried over magnesium sulfate, and evaporated under reduced pressure to give 4-benzyl-2,2-dimethoxymethylmorpholine (31.79 g) as an orange oil.
