실험 절차

2,6-Dimethylmorpholine (a mixture of trans- and cis-isomers (1.0 g, 8.7 mmol) and TEA (1.34 ml, 9.6 mmol) were dissolved in anhydrous ether (50 ml) and cooled in ice bath. To the above mixture was added dropwise a solution of chloroacetyl chloride (0.69 ml, 8.7 mmol). Then the mixture was warmed to room temperature and stirred for 3 hours. The mixture was washed with water, dried and evaporated under reduced pressure. The residue was purified by column chromatography (EA/PE=1/1) to afford the title compound (0.79 g, yield 47.5%).
