19.3 g(139 mmol) of potassium carbonate was added to 200 ml of dimethylformamide, and then the solution was heated to dissolve potassium carbonate. After cooling to room temperature, 8 ml(70 mmol) of ethyl bromoacetate and 10 g(70 mmol) of 1-naphthylamine were added to the solution, which was then stirred for 48 hours. DMF was removed under reduced pressure and ethyl acetate was added to the residue. The ethyl acetate layer was washed with water 4 times and saturated sodium chloride solution. Ethyl acetate was removed under reduced pressure, and then column chromatography was performed using a mixed solution(9:1) of hexane and ethyl acetate as an eluent to obtain 12 g of the title compound(Yield 75%, MW 229).
