Reaction Steps
2.0 g of ethyl 2-acetyl-3-oxo-butyrate was mixed with 5 drops of 1,8-diazabicyclo-[5.4.0]-undec-7-ene. Over 10 minutes, 2.7 g of ethyl acrylate was added dropwise. The mixture was stirred for 30 hours at room temperature, 2 ml of acetic acid was added to neutralize the base, and the mixture was extracted with an aqueous sodium carbonate solution and water. Fractional distillation yields 1.5 g of 2,2-diacetyl-1,5-pentanedioic acid diethyl ester (purity: 70%; colorless).
