以4-氯乙酰乙酸甲酯為原料合成丁二酰丁二酸二甲酯的一般步驟：在攪拌條件下，將4-氯乙酰乙酸甲酯（10g，0.06mol）緩慢加入至含有碳酸鉀（17g，0.12mol）和DMSO（50mL）的混合溶液中。反應(yīng)混合物首先在室溫下攪拌3小時，隨后升溫至60℃繼續(xù)攪拌10小時。反應(yīng)完成后，將混合物冷卻至室溫，用適量水稀釋，隨后過濾。濾液用乙醚進行萃取，萃取液經(jīng)無水硫酸鎂干燥后，通過蒸餾去除溶劑，得到黃色晶體產(chǎn)物（14g，產(chǎn)率52%），熔點為152-153℃。產(chǎn)物的結(jié)構(gòu)通過1H NMR和13C NMR光譜確認：1H NMR (δ, ppm): 3.20 (s, 2H, CH2), 3.80 (s, 3H, CH3O), 3.90 (s, 3H, CH3O), 7.45 (s, 1H, CH=), 9.80 (s, 1H, OH), 12.10 (s, 1H, OH); 13C NMR (CDCl3, δ, ppm): 28.42, 52.33, 53.07, 95.94, 118.00, 120.05, 151.32, 168.00, 171.36。元素分析結(jié)果與理論值相符：實測值（%）：C 52.78, H 5.17；理論值（C10H12O6，%）：C 52.63, H 5.26。
