실험 절차
To a solution of 34.96 g (0.231 mol) of N-ethyl-3-hydroxybenzylamine in 200 ml of dimethylsulfoxide were added 25.64 g (0.231 mol) of 1,3-dichloropropene (E/Z=2/1) and 16.7 g (0.121 mol) of ground potassium carbonate under ice cooling. The mixture was stirred for 4 hours at 50° C., poured into 250 ml of ethyl acetate, washed with 200 ml×2 of water and 200 ml of saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was subjected to-silica gel chromatography (n-hexane→n-hexane/ethyl acetate=9/1). The desired fractions were put together-and concentrated under reduced pressure to obtain 26.2 g (yield: 50%) of the above identified compound as an oil.
