Ethyl Acetate → (E)-3-Chloro-N-methyl-N-(1-naphthylmethyl)-2-propen-1-amine

To a solution of 9.84 g (57.5 mmol) of N-methyl-1-naphthalenemethanamine in 60 ml of dimethyl sulfoxide were added 5.5 ml (60 mmol) of 1,3-dichloropropene (E/Z =9/1) and 8.28 g (60 mmol) of potassium carbonate under ice cooling. The mixture was stirred for 6 hours at room temperature, poured into 250 ml of ethyl acetate, washed with 150 ml ×3 of water and 150 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 10.86 g (yield: 77%) of the above identified compound as an oil.
