实验步骤: To a solution of 3.30 g (20 mmol) of N-propyl-3-hydroxybenzylamine in 20 ml of dimethyl sulfoxide were added 1.82 g (20 mmol) of 1,3-dichloropropene (E/Z=2/1) and 1.38 g (10 mmol) of ground potassium carbonate under ice cooling. The mixture was stirred for 1.5 hours at room temperature and for 3 hours at 50° C., poured into 70 ml of ethyl acetate, washed with 50 ml×2 of water and 50 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 2.29 g (yield: 48%) of the above identified compound as an oil. washed with 50 ml×2 of water and 50 ml of saturated sodium chloride aqueous solution dried over anhydrous magnesium sulfate concentrated under reduced pressure concentrated under reduced pressure to obtain 2.29 g (yield: 48%) of the
