Reaction Steps

After 1.24 g (6.1 mmol) of dimethyl 4-(methoxymethylene)2-pentenedioate obtained in Example 1-1 was dissolved in 10 mL of DMF, 830 g (6.1 mmol) of 4-dimethylaminoaniline was added to the solution. Afterward, the resulting reaction solution was stirred under reflex at about 50° C. for about 3 hours. After termination of the reaction was determined by liquid chromatography, the solvent was removed in vacuo and was then washed using brine, followed by drying using magnesium sulfate and filtration. After distillation under reduced pressure, the resulting product was purified using column chromatography (hexane:ethyl acetate=1:1) to obtain a target compound (Actual yield: 357 mg, Yield ratio: 21%).
